Uses Of Neodymium Magnets

Neodymium magnets are permanent magnets obtained when an alloy made of Iron, Neodymium and Boron is magnetized. This alloy, NdFeB, forms the most powerful magnet known to man when magnetized. There are many uses of this powerful magnet.

The most familiar eco-friendly use of Neodymium magnets is powering hybrid and electric locomotives. There is an ongoing research to make increase the resistance of these magnets to high temperatures. This will make it possible for heavy engines to be powered using Neodymium magnets. If magnets which can resist temperatures above 392 degrees Fahrenheit can be produced, the technology will be more eco-friendly since there will be little or no cooling required.

Neodymium magnets are also used in wind turbine generators which produce green energy. One ton of Neodymium magnet is required to produce one watt of electricity. For this reason, governments and Non-governmental organizations are giving incentives to spearhead the development of this technology.

These powerful magnets are also used to repel sharks and rays. The Bimini Biological Research center discovered that these large fish usually swim at least 10 inches away from the field produced by neodymium magnets. This low-tech invention can be used to protect sharks and endangered ray fish from humans.

While NdFeB magnets were discovered in 1885, it was not until 1982 when industrial applications of this magnet was practical. This was partly due to the development of lightweight magnets. The cost of neodymium magnets has gone down in the last few years due to improved technology. Their application has also increased to more areas in life.
