How do magnets demagnetize?

Before we explain how magnets demagnetize – lose their magnetism, it may be helpful to note: Permanent magnets are made of elements known as ferromagnetic materials by exposing them to a magnetic field using electric current. Using a magnetizing fixture that directs current through the non-magnetized part, electron spins in these metals are lined up, or polarized, […]
