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.
