Have you ever wondered how magnets work?
2. Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
3. A permanent magnet is a magnet that retains its magnetic properties in the absence of an inducing field or current. Example would be a refrigerator magnet
Temporary magnets are things that act like a permanent magnets when they are within a strong magnetic field, but they lose their magnetism when the magnetic field disappears. Examples would be paperclips and nails and other soft iron items.
