Magnetic Materials

The Magnetic Materials team has a long track record of material innovation that has helped in power generation and energy conversion. The team has invented techniques for soft and hard magnetic materials and magnetocaloric substances. They comprise crystalline, nanocrystalline and nanocomposite structures. Our innovations have been an advantage to GE Aviation, Power, Renewable Energy, and Transportation.

Permanent magnets

What is a permanent magnet?

A permanent magnet is an object made from a material that is magnetic and generates its own permanent magnetic field. A common example is a refrigerator magnet used to hold notes on the refrigerator’s door.
