1. Ferromagnetic Metals (Iron, Nickel, Cobalt):
* If the metal is ferromagnetic, it becomes magnetized.** This means it will gain magnetic properties and become attracted to the magnet.
* The strength of the induced magnetism depends on factors like:
* Strength of the magnet: A stronger magnet induces stronger magnetism in the metal.
* Type of metal: Some metals are more easily magnetized than others.
* Duration of rubbing: The longer you rub, the stronger the induced magnetism.
* The magnetization is temporary** unless the metal is a "hard" ferromagnetic material.
2. Non-ferromagnetic Metals (Copper, Aluminum, Gold):
* If the metal is non-ferromagnetic, it does not become magnetized**. It will not be attracted to the magnet.
* The metal may experience a slight temporary magnetic field**, but this is negligible and does not affect the metal's properties.
Example: Rubbing a magnet against a paperclip (made of iron) will cause the paperclip to become a temporary magnet.
It's important to remember that:
* You can't turn any metal into a permanent magnet by rubbing it with another magnet. Only ferromagnetic metals can be magnetized.
* If you want to make a permanent magnet, you need to apply a strong magnetic field to a "hard" ferromagnetic material. This is usually done using electromagnets.
