Question

what change occur in the molecular magnet when magnet is demagnetized?

Answer 1

Answer:

Curie Temperature

At this temperature, the ferromagnetic material becomes paramagnetic. Even if you cool the magnet, once it has become demagnetized , it will not become magnetized again. Different magnetic materials have different Curie Temperatures, but the average is about 600 to 800 degrees Celsius
