1) Magnets have north and south poles that attract or repel each other depending on their orientation, similar to electric charges. The magnetic force follows a law analogous to Newton's law of gravity and Coulomb's law for electricity. 2) If a magnet is broken in half, each new piece becomes a smaller magnet with its own north and south poles, rather than separating the original poles. 3) Passing an electric current through a coil of wire or loop creates a magnetic field. The direction and strength of the magnetic field can be determined using the right hand rule.
