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 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.

What are temporary magnets?

Temporary magnets are magnets which act like permanent magnets when they are within a strong magnetic field, but lose their magnetism outside the magnetic field. Examples would be paper clips, nails, and other soft iron items.

Who discovered magnets?

Some say that Magnes,a shepherd, discovered them discovered magnets when his shoe nails stuck to a rock containing magnetite. Others say that the Greeks discovered natural magnets.
