"Demagnetization is the reduction or elimination of magnetization. One way to do this is to heat the object above its Curie temperature, where thermal fluctuations have enough energy to overcome exchange interactions, the source of ferromagnetic order, and destroy that order. Another way is to pull it out of an electric coil with alternating current running through it, giving rise to fields that oppose the magnetization. " - How does demagnetization work

WebApr 10, 2024 · Use a Hammer. A small piece of steel can be struck with a hammer to demagnetize it. Place the item on a hard, secure, non-metallic surface and hit it sharply a few times with a hammer. The shock of being struck transmits energy through the steel, which rearranges the order of its atoms and lowers its magnetic output. WebDemagnetized cards are not extremely expensive. However, as a general rule, it’s not recommended to fix them. Some people recommend applying a simple life hack, such as putting some tape over the magnetic stripe, but this is no guarantee that the card will work.
