Explanation:

Compass: Configurations of north and south pole pairs.

Magnetic dipoles: A very small bar magnet that can pivot freely in response to a magnetic force.

Magnetic Field: Their length is proportional to the strength of the field at their location.

Magnetic Field Lines: They never cross one another and have densities proportional to field strength.

Magnetic Field Vectors: Trace out the direction and strength of the magnetic force.

Magnetometer: A device used to measure the strength and direction of a magnetic field.
