What is a simple definition of magnetism?
Magnetic forces are created when two magnets or objects with magnetic fields interact. Magnets can attract or repel depending on the direction of the magnetic fields. The strength of the magnetic force depends on the distance between the objects and the strength of the magnetic fields.
Magnetic Field: A region of space around a magnet or an electric current in which a magnetic force can be detected. Magnetic Force: A force that acts between two magnets or between a magnet and an electric current. Poles: The two ends of a magnet where the force of the magnet is strongest.
The force of a magnet is strongest at its poles. Some materials, such as aluminum, copper, and gold, are not magnetic. The Earth has its own magnetic field and it is caused by the motion of liquid iron in its outer core.
