How magnet loose magnetic effect on heating

Posted by Akash Yadav 7 years, 4 months ago

CBSE > Class 12 > Physics

1 answers

Lucky Momin 7 years, 4 months ago

When exposed to heat, the magnetic domains, which were normally aligned in the same direction, gain energy due to heat and lose orientation, thus becoming randomized in their alignment, and if the heat energy persists, then the magnet keeps on losing its magnetism until it doesn’t remain a magnet any more.
