Question

Why will dropping or heating a magnet weaken it?

Answer 1

Dropping and heating causes movement and vibration, and thus the aligning of the domains gets weakened and hence the magnetic field gets weakened. When it is heated above the Curie temperature, the ferromagnetic properties disappear and the ferromagnet transforms into paramagnet.

Answer 2

Thank you for this explanation I have to do a project for my mom because I am home schooled so this is useful thank you 🙏
