Abstract

Permanent magnet is widely used in today’s application such motors we used in car or generator in power stations. Materials commonly used are neodymium, alnico, and also soft ferrites. Its unique ability to retain its magnet force for such a long time is one of the attributes it excels in. However, loss of magnet’s strength or demagnetization can bring major impact in applications. External field or electric current is one of the method where a magnet can be magnetized and demagnetized by altering the number of domains of electrons which the mechanism of magnetism is present. Permanent magnet – permanent magnet interactions in cyclic motion resembles what happen in both motor and generators. Their magnetic strength is indeed all acting differently before, during and after the application to be specific, in cyclic motion. Hence, further research must be done followed by in-depth analysis to know how these magnets would react under cyclic motion.
