Question

Explain how can a magnet loose it’s magnetism.
Please tell it’s urgent

Answer 1

Answer:

Elevated temperature: Magnetic materials lose magnetism as they heat, but they regain magnetism when cooled provided the maximum temperature is below their Curie temperature. Above the Curie temperature, a magnet permanently loses all or some of its magnetism.

Answer 2

Explanation:

(Why is a non-permanent, but long lasting, magnet called a permanent magnet?) magnet is cut in two?) Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment.
