and many alloys of these metals like steel
and alnico are magnetic.
A magnet has two magnetic
poles (north and south seeking
poles).
Magnets exert either a force of
repulsion or attraction.

Electromagnetic inductionis a
phenomenon of inducing a
voltage in a conductor by
changing the magnetic field near
the conductor.
