Power of Large Rare Earth Magnets

The large rare earth magnets are very powerful permanent magnets. They are made of the material like neodymium or dysprosium. It can be very effectively used in power massive wind turbines, which is capable of generating not less than 2 million watts of electricity. The power of the generator depend directly the force of the magnet. So the stronger the magnet, greater potent the generator will be. The rare earth magnets are really strong having a huge power of magnetic field. So it is really difficult to control the power and use it the intended function to get best utilization out of it. The recent trend is to make smaller rare earth magnets with less powerful magnetic field which is made of nano-particles. The rare earth magnets are also useful in military to build up weapon systems.

The rare earth magnet is good at observing temperature. That is the reason, why the Neodymium Magnet is not getting potential demagnetization easily. The rare earth magnets made of Samarium cobalt is stronger than neodymium iron boron magnets. All the rare earth magnets can resist with a temperature of 20 degrees Celsius. However the neodymium magnets cannot withstand in an increased temperature. It can cause ill effect to neodymium magnets through demagnetize it temporarily. The other feature to be considered is that, thicker magnets greater will be magnetic field.

If you put Neodymium Magnet against corrosion, you will find that the huge rare earth magnets may break due to the large surface area. Even though the damage caused will not influence the magnetic properties present in it. So, surface coatings are often proved helpful in preserving the structural integrity of the magnets. Samarium cobalt magnets are subject to extremely corrosion-resistant.

There are some drawbacks associated with machining rare earth magnets. Always prefer use diamond tooling for the strong Neodymium Block Magnet or abrasive grinding depending upon the alloy. The less brittle magnets like Neodymium iron boron magnets are easy to machine than a samarium cobalt magnet.

All the rare earth magnets do not behave in the same manner. Different Neodymium Magnet of diverse alloys will be used for different application. For example a rare earth magnets with the potent of high intrinsic coercive force, is useful for electromechanical operations.

It is advisable to consider the magnetic field of the rare earth magnet before putting it into action for your design. Rare earth magnets have a powerful magnetic field and a single direction of magnetization. It can magnetize other object through simple strokes with the original magnet in one direction.
