Chemically, they have a tetragonal crystalline body structure. Originally priced heavily, they have recently become affordable for daily use purposes and are a new product in the market.
The magnets were developed for the first time in the year 1982 by General Motors and Sumitomo Special Metals. The strength is greater compared to the magnets made of ferrite or alnico. They have slowly and gradually replaced other varieties of magnet used for various applications.
The strength of the magnetic field produced by them can measure up to around 1.5 teslas.
Rare Earth Neodymium magnets are the strongest type of permanent magnets made from an alloy comprising of neodymium (Ne), iron (Fe) and boron (B) in varied proportions. They are often referred to as “NdFeB” magnets because of their constituents.
Different Properties of Rare Earth Neodymium magnets
The structure of Rare Earth Neodymium magnets is designed specifically to have a high uniaxial magneto-crystalline anisotropy.
This allows the specific compound to have a high coercivity value. With a magnetic field value of 1.5T, they even have a relatively high value of saturation magnetization. The maximum energy being directly proportional to the saturation magnetization, it has the capacity for the storage of magnetic energy in large amount.
The properties of the Rare Earth Neodymium magnets largely depend upon the constituent elements and the manufacturing technique. The crystalline structure gives them a high value of magnetic anisotropy.
It implies that a small crystal of the material can be magnetized easily in a particular direction but it will resist doing the same in the other direction.
Various Applications of Rare Earth Neodymium magnets
Rare Earth Neodymium magnets are used almost everywhere in today’s world. The great strength of the magnet facilitates their usage for both large and small magnets. It is used extensively in preparing toys for children and adults.
They are used in welding clamps to hold two or more pieces of metal together.
They have similar applications in drilling and machining. They find applications in oil pans and oil filters to filter the metal chips out of the oil.
They are even used as stud finders to locate hidden nails in the walls and flooring. They are used abundantly in the preparation of various computer hard drives, dynamos of bicycles, audio speakers and headphones, fishing reel brakes and in making permanent magnet motors in cordless tools.
These magnets play a pivotal role in generating electricity in shaking motion in the construction of self powered flashlights.

Magnets
A magnet is usually a substance or an item which can generate a magnetic field around its surroundings.
They can attract various ferromagnetic substances like the iron. They also have a property of repelling when they are kept with other magnets.
There are different varieties of magnets in different shapes and sizes available for both used in home and industries.
What are the various types of magnets available?
There are three main types of magnets which are temporary magnets, permanent magnets and electromagnets. Permanent magnets are used in everyday life like that in the refrigerator. They are generated when a magnetic substance has a prolong magnetic field. They retain the degree of magnetism.
Temporary magnets are those magnets which acts like a permanent magnet only when they are place inside a strong field of magnetism. But they lose their magnetism as soon as the field disappears. Soft iron nails and paperclips are the common examples of the temporary magnets.
Electromagnets are those magnets which contains an iron core usually surrounded by coils of wire. When current flows through the wire, it acts as a permanent magnet. The polarity and the strength of a magnet generated by the electromagnet can be adjusted by varying the strength of the current which flows through the wire.
It is also depended on the alteration of the direction of the flow of the current.
What are the uses of the magnets?
There are different applications of magnets in various fields. They are used in the common items used at home to complicated devices in industry. They are very important in everybody’s life and are pretty useful.
They are used widely in cassettes, hard disk and floppy disks. In industries they are used as separators, pullers, sweepers, welding and conveyors. ATM cards, debit cards and credits also uses magnet which is used in the magnetic strips. This magnetic strip helps in encoding the details about a particular individual about his bank details and account.
They are also widely used in microphones and speakers. In the health sector, magnets are used in MRI where various different organs of the human body is scanned for surgical reasons. They are used in many jewelry objects like earrings, bracelets, necklaces and pendants.
Magnets are also used extensively in many magnetic therapy equipments which include magnetic massager, magnetic waist belts, magnetic mattresses, knee magnets and many others. Generators and electronic motors widely use the magnet.

Solenoid Valves
What are Solenoid Valves
As the name indicates, valves are gateways for controlling the flow of an object. In case of solenoid valves, the object is either liquid or gaseous in nature. The solenoid transmits the electric current through which the valve is controlled.
Due to the safety offered by solenoid valves as well as the ease of use, they are amongst the commonest elements used in fluidics. While the plunger-type actuator is the most widely used type of solenoid valves, others like pivoted-armature actuators and rocker actuators are also in vogue.
The basic design of solenoid valves comes with either two or three ports. In case of a two port valve, opening and shutting down the flow of the fluid is the only task of the valve. Solenoid valves coming with three ports are used for switching the flow between two ports.
Classification and Working Principle of Solenoid Valves
On the basis of designs, solenoid valves are divided into several categories. The most basic one way valves are classified into three major types based on the number of valves used, type of power supplied and the number of positions and ways.
Solenoid valves consist of two major parts- the solenoid and the valve. Electrical energy supplied to the solenoid is transformed into mechanical energy which is used for opening or closing the valve. Depending on whether the valve is direct acting or diaphragm piloted, the amount of fluid passing through the valve varies.
The basic principle behind the proper functioning of solenoid valves is the maintenance of pressure difference between the input and the output. Input pressure always has to exceed the output pressure for solenoid valves to function. In case of the input pressure falling below the output pressure, the valve will open automatically.
The power consumed by solenoid valves depends on the position of the solenoid with respect to the valve.
Application of Solenoid Valves
Though solenoid valves are most widely used in fluid control, it is also used for pharmacology experiments for patch-clamps. In more traditional usage, it is used in fluid power pneumatic and hydraulic systems.
Washing machines and dishwashers also utilize solenoid valves for controlling the flow of water into the appliance. Dental chairs also make use of solenoids for the purpose of controlling air flow.
Besides these, automatic irrigation sprinkler and paintball industries are two other areas of application of solenoid valves.

Neodymium magnets
Meet the new attraction -the Neodymium magnets
Ever since it began to be in use, technology is getting a stronger grip on our lives. We cannot imagine our world today without technology in it. What's the secret? Well, it's not much of a secret. Every kid knows that technology is here to improve our lives, to make it easier on us, in this fast moving world.
Except for the obvious technological inventions and fields, we were recently introduced to an intriguing and promising field - the rare earth magnets field. Amongst the several types of these magnets we recognize a type named on a large scale - the Neodymium magnets. These very special magnets are the new game everyone wants to play with. Scientists are exploring this territory for only a few decades and already we can see the results in practice.
If once we thought electricity was the invention of the century or even the millennium, now we understand that planet Earth still holds great mysteries for us to discover. As mentioned, Neodymium magnets are one of those mysteries we're beginning to unlock. They have so many uses, that it would be wrong of us to ignore their existence.
With the kindest help from our beloved planet and the assistance of scientists and businessmen, there's no limit to the progress we can reach. As you know, human kind reached its place in top of the food chain by using his brain to get to higher places, to places "where no man has gone before".
What are Neodymium magnets good for?
In the short time we had to research and explore this newly exposed territory, we can confidently say that all technological, medical and electronic fields will have a great benefit from using any kind within the several kind of Neodymium magnets.
These magnets are super strong and condensed, and may be used in various forms and conditions - whatever will answer your requirements. As such, medical devices built using Neodymium magnets can function better and in a more accurate way (just like the MRI scanner works so much better than a simple CT scan). Moreover, electronic devices may be released from their 'leash', and perform without being plugged to an electricity connection.
Furthermore, the known ultra strength of the Neodymium magnets has opened up a whole new aspect to consider while inventing and developing devices that wouldn't normally involve magnets.
We haven't heard the last from Neodymium magnets yet
From looking at its usage up until now, we can guarantee that we'll be hearing a lot more from the subfield of Neodymium magnets. From the way things look now, it's going to do good to mankind, and just as important - to our planet Earth.

Ferrite Magnets
The way so far for Ferrite magnets
Opposites attract, likes repel. The little phrase here used repetitively for centuries, with its various meaning or undertones, owes its origin from the phenomenon of magnetism, when it was observed that two opposite poles of a magnet attracted while the similar poles repelled. This was just an example of how magnetism has influenced human society.
We all know that the Earth itself consists of a huge magnet forming its’ core and magnetism influences nearly every aspect of life on earth. Be it natural events like movements in the Earth’s crust, or in devices like the compass, ever faithful friend of sailors or even anyone who just feels a bit lost, or devices like the electric generator or motor, forming the driving force of the Industrial Revolution.
Magnets have truly been as much of magic as the Ancients thought of them. Throughout history, magnets have almost always been made primarily of Iron. These are called Ferrite magnets, consisting mainly of Iron (III) oxide along with alloys of some metals such as magnesium, zinc, etc.
Under the surface of Ferrite magnets
Ferrite magnets are synonymous with magnets. Since ages, magnets have always been Ferrite. Abundantly available in the Earth’s crust, Iron can easily be magnetized into strong permanent magnets. Ferrite magnets are usually manufactured by pressing Ferrite powder in a die and then sintering it.
After these processes, the magnets produced generally have to go through a few more machining processes to improve their physical strength, tolerances and surface finish. Another alternate method of manufacturing involves injection moulding. This process albeit more expensive, produces magnets with better physical properties and tolerances.
Ferrite magnets are classified soft or hard according to their low or high coercivity of respectively. The magnetism of Ferrite magnets however is lesser than those of Alnico magnets, and much lower than rare earth magnets with maximum magnetism around 0.35 Tesla (Unit of magnetism)
The uses of Ferrite magnets today
While the magnetism of Ferrite is nowhere near those of Alnico and Rare-earth magnets, they still have a very big stronghold in applications, primarily because they are inexpensive and safe to use. These advantages have resulted in very widespread application of these magnets.
Some common examples are:
- Electric Motors
- Transformers
- Electromagnets
- Loudspeakers
- Magnetic Recording tapes
- Magnetic Ink
- Electromagnetic Instruments, etc
- Refrigerator magnets
- Household magnets, etc
The inexpensiveness of Ferrite magnets has kept them in the industry, although now being fast replaced by Alnico and Rare-earth magnets.

Fleet Management System
Fleet Management System - Not Just Ships
Though the term may lead a layman to think about things to do with maritime navigation, fleet management system actually encompasses the whole range of vehicles- from cars to ships- that are used by a company for its business purposes.
The basic functions of fleet management are the financing of the vehicle, their maintenance, safety, supply of crew, speed and fuel management and assuring the compliance with all government regulations.
It basically aims towards reducing the risks involved in investing in vehicles by the companies. The convenience offered by the fleet management system is so much that units employed in this facility are estimated to rise from 1.5 million to 4 million between 2009 and 2014.
Fleet Management System - How it Works
It is primarily concerned with keeping track of the vehicles en route to their destination. This is done with GPS, GLONASS or Cellular triangulation.
Depending upon the route to be followed by the vehicle, fleet management system uses either satellite or territorial communication and thereby receives information about the vehicle at all points of time. This information ranges from the real-time location of the vehicle to its fuel consumption and so on.
The information gathered thus also aids in forming the profile of the driver. With the advancements made in the field of fleet management system, it is now within the scope of the owners of the vehicle to stop, decelerate and prevent loss of cargo in case of a theft. It also provides the drive the option to stop the vehicle in case of an emergency and notify the concerned persons to act immediately.
Companies opting for fleet management are also less hassled by the legal issues and can concern themselves chiefly with the cargo.
Fleet Management System - Safety First
With road accident laws becoming more stringent by the minute, more and more companies prefer to spend on the management of fleets rather than bear the heavy cost of litigations. As the companies are held responsible for accidents involving their employed vehicle, reducing the number of accidents is a major concern of Fleet Management System.
This is achieved largely by identifying the vehicles and vehicular parts that need to be replaced or repaired. Also by maintaining a record of the behavioral pattern of the driver, any threat arising from that aspect is nullified.
Thus, fleet management system not only manages to save millions of dollars of the companies, but more importantly, invaluable human lives.
Air Valves
What are Air Valves?
Air valves are suction valves that work in order to cut down the emissions in the exhaust gases coming out from the internal combustion engines. Air valves are taken widely in use in factories, where they are installed to provide a sustainable amount of supply by compressing the atmospheric air.
Some of these air valves even employ air pressure against a piston or diaphragm and help in the production of linear or circular movements to allow the proper functioning of a larger valve.
Working principle of Air Valves
The working procedure of air valves is pressure dependent. During the time when the exhaust valves of an engine are open, the pressure in the exhaust manifold is comparatively greater than the normal atmospheric pressure. Specific changes in the configuration of the exhaust manifold are made so as to conjure positive and negative pulses during the operative phase of the cycle by designing it on the lines of a diffuser.
Normal air valves generally have three openings. The first opening is connected to the manifold vacuum, the second to the exhaust pipe and the third is kept open in the atmosphere. On the application of a negative pulse in the exhaust, air from the atmosphere rushes inside the exhaust manifold via a one-way reed valve.
The collected air then starts oxidizing the carbon monoxide and hydrocarbons in the exhaust. Air valves also work as a component of air cut valve system to cut down the cost in the usage of different machineries. The air cut valves system comprises essentially of a diaphragm loaded with spring and a shaft that is generally attached to the bottom. A manifold vacuum applied over the diaphragm near the shaft end, completes the system.
At the time of deceleration, the vacuum in the engine rises against the spring and gives the shaft a push in the downward direction. This blocks the opening that acted as the passage of atmospheric air to the exhaust.
The negative pulse created during deceleration facilitates the manifold vacuum to block and cut off the air passage to the exhaust manifold. The air cut valve system is the reason behind backfire or popping during deceleration on the addition of an open exhaust to motorbikes.
Applications of Air Valves
Air valves have varied applications in today’s world. They are used extensively in agricultural and landscape irrigation laterals. Air valves are also used in water supply as they facilitate high velocity air discharge and prevent water hammering incidents. Air valves are used in huge numbers in factories to cut down the emission and increase the supplies by compressing the exhaust air.
