Key Takeaways: Demagnetization
Demagnetization randomizes the orientation of magnetic dipoles.
Demagnetization processes include heating past the Curie point, applying a strong magnetic field, applying alternating current, or hammering the metal.
Demagnetization occurs naturally over time. The speed of the process depends on the material, the temperature, and other factors.
While demagnetization may occur by accident, it is often performed intentionally when metal parts become magnetized or in order to destroy magnetic-encoded data.
