The presence of magnetic fields best explains why a magnet can act a distance on other magnets or on objects containing certain metals.

Magnetic fields are lines of forces around a bar magnet.
These lines of forces attracts and repels other magnetic bodies and metallic bodies round it.
Magnetic lines of forces originates at the north pole and enters in the south pole.
Areas around a magnetic body are bounded by force fields.
A magnet has permanent magnetic fields round it.
