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.Know More
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.
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.
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.
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.Full Answer >
To demagnetize a magnet, cause disorder to the unit magnets within the magnetic material. Strike the magnet first with a hammer, heat it strongly, and then subject it to AC current to eliminate magnetic ability completely.Full Answer >
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.Full Answer >
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.Full Answer >
