There are two kinds of magnets temporary and permanent magnets.Temporary magnets will loose all or most of their magnetic properties. But a permanent magnet will retain or keep their magnetic properties for a very long time.
Temporary magnets are made of such materials as iron and nickle. The materials are known as soft magnetic materials because they usually do not retain their magnetism outside a strong magnetic field.
There are two essential ingredients for generating a magnetic field. Those two ingredients are , Magnetic Material or currents.
You can create a temporary or permant magnet by what kinds of metals you use. By stroking a permant magnet onto a pure metal in one direction many times, soon it will become temporarly magnetized.
what causes this is the Magnetic Domain by witch tapping the magnet and metal you nudge any stubborn domains into alignment.
Currents can be used to make a magnet by getting a bar of iron and wrapping it with wires then run a current through the wires.
Permanent magnets are made by placing pieces of iron cobalt, and nickle into strong magnetic fields. Permanent magnets are mixtures of iron, nickle, or cobalt with other elements. These are known as hard magnetic materials.
There are many different metals but only three pure metals can be magnetized. These are iron, nickle and cobalt. If you mix pure metals together their magnetic charactistics can be alterd. The natural form of a magnet is called a lodestone, it contains iron. When man mixed the pure metals together ( ie. iron, nickle and cobalt ) we created an even stronger magnet which are the ones we use most today.
