Q:

How do I demagnetize something?

A:

Quick Answer

A magnet can be demagnetized with heat, hammering or an electric current. A metal behaves as a magnet when all its units or domains are aligned in one direction. When this alignment is destroyed and made random, the magnetism is also destroyed.

Full Answer

When heating a magnet, it must be heated for a long duration. Hammering should be done at both poles of the magnet. When an AC current is passed through a solenoid, a magnetic field is created around the object, which destroys the alignment of domains in the object to be demagnetized. The object to be demagnetized can also be rubbed vigorously in both directions with a metallic object, which can cause it to lose its magnetic properties.

  • Q:

    How can you demagnetize metal?

    A:

    Demagnetizing metal is done by displacing the dipoles that give it the magnetic qualities. This can be done by hitting the metal with a hammer once it's aligned correctly and heating it above its curie temperature.

    What are some examples of magnets?

    A:

    One example of a magnet is a refrigerator magnet. These are also called permanent magnets because they always retain a certain degree of their magnetism. There some other general categories for magnets, such as temporary magnets and electromagnets.

    Is aluminium attracted to a magnet?

    A:

    Aluminum is not attracted to a magnet unless it is in a strong magnetic field. In strong magnetic fields, aluminum can become slightly magnetic. Under normal circumstances, aluminum does not exhibit magnetism; aluminum can produce an electrical current when it interacts with a magnet.

    What is a U-shaped magnet?

    A:

    A U-shaped magnet derives its name from its shape and has both a north and a south pole located in the same plane at the open end of the magnet. This type of magnet is also called a horseshoe magnet.
