Magnets!

Have you ever wondered how magnets work?
What is a Magnet?
A magnet is a piece of iron that has its component atoms so ordered that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.
Temporary Magnets
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.
Magnetism

Permanent Magnets
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
