It is theories based upon observations of its effects on 'magnetically capable' elements, such as gold, copper, silver, and iron.
Magnetic induction is the principle by which electricty flows into and becomes useful in your house.
Magnetism is directly tied to 'electron flow' or alternating polarization of valence electrons from one atom to another.
Magnets cause motion for bullet trains, allow motors to work, and even keep your earings on.
Magnetism is how hammerhead sharks find food with their 'metal-detector' - like heads.
Magnetism is how ocean vessels navigate the earth and hikers find their way.
