Answer:
Demagnetize a Magnet by Heating or Hammering
Demagnetize a Magnet by Heating or HammeringIf you heat a magnet past the temperature called the Curie point, the energy will free the magnetic dipoles from their ordered orientation. The long-range order is destroyed and the material will have little to no magnetization. The temperature required to achieve the effect is a physical property of the particular material.You can get the same effect by repeatedly hammering a magnet, applying pressure, or dropping it on a hard surface. The physical disruption and vibration shake the order out of the material, demagnetizing it.
Self De.magnetization
Self D.emagnetization Over time, most magnets naturally lose strength as long range ordering is reduced. Some magnets don't last very long, while natural demagnetiza.tion is an extremely slow process for others. If you store a bunch of magnets together or randomly rub magnets against each other, each will affect the other, changing the orientation of the magnetic dipoles and lessening the net magnetic field strength. A strong magnet can be used to demagnetize a weaker that has a lower coe-rcive field.
Apply AC Current
Apply AC CurrentOne way to make a magnet is by applying an electrical field (electromagnet), so it makes sense you can use alternating current to remove magnetism, too.
