What are magnets?
Magnets are a piece of iron (or an alloy or other material) that has its component atoms ordered so that the material exhibits properties of magnetism, such as attracting other iron-containing objects or aligning itself in an external magnetic field.

What is magnetism?
Magnetism is a physical phenomenon made by the motion of electric charge, resulting in attractive and repelling forces between objects.
What is an electromagnet?
An electromagnet is a soft metal made into a magnet by the passage of an electric current through a coil surrounding it.
What are superconductors?
A superconductor is a substance that can conduct electricity or move electrons from one atom to another with no resistance. This means there is no heat, sound, or any other form of energy would be released from the substance.
What are permanent magnets?
A permanent magnet is a magnet that retains its magnetic properties in the absence of another magnetic field or current.
