Q:

How do you magnetize something?

A:

Quick Answer

Using an existing magnet, you can magnetize everyday household items that contain iron, cobalt or nickel, which are metals that exhibit the property of ferromagnetism. Ferromagnetism is a subatomic property of some metals created by the structure of the electron clouds around the atoms. When the electrons of the metals align in a particular way, the metal produces a magnetic field.

  1. Gather the necessary materials

    Select the strongest magnet available in order to magnetize other metals. When searching for something to magnetize, you can choose from a variety of objects, such as nails, screws, tools and even paperclips, as long as they contain the correct type of metal.

  2. Align the electrons

    Stroke the magnet in one direction along the chosen item. Don't rub back and forth. Alternatively, you can strike the object repeatedly with a hammer. Some objects become magnetized by the action of the Earth's magnetic field if they are knocked loose first. This method is less likely to work than the rubbing method.

  3. Test the new magnet

    Hold the object near other metallic items to see if it's now magnetized. If it isn't, try repeating step 2. If the object still doesn't become magnetized, it probably contains nonmagnetic materials. Select a different object and try again.

  • Q:

    What is one way you can destroy a magnet's magnetism?

    A:

    The NDT Resource Center describes exposing a magnet to a reversing and decreasing magnetic field as one way to remove its magnetic properties. This is not the most effective method of demagnetizing a magnet, but it is far simpler to perform than the most effective method, which involves heating the magnetic material to a high temperature. Exposing a magnet to a reversing magnetic field demagnetizes it almost completely.

  • Q:

    How are magnets made?

    A:

    A magnet is made of any of a group of metals called ferromagnetic metals. Ferromagnetic metals contain many small magnetic fields called domains. In their natural state, the magnetic fields of these domains point in different directions. To create a magnet, the magnetic fields must align in the same direction.

    Is lead magnetic?

    A:

    Lead is not magnetic in the sense that it is neither attracted to nor repelled by a magnet. Lead cannot be charged up via contact with a magnet unlike what happens with many other metal objects, such as nails, staples and iron shavings.

  • Q:

    Does a magnet stick to stainless steel?

    A:

    Depending on the composition of the stainless steel, a magnet may or may not stick to it. Stainless steels are alloyed steels containing iron, carbon and other components. The iron is strongly magnetic, but the other components interfere with the iron atoms' ability to line up in the same direction, which is what gives it strong magnetic properties.
