Electromagnetics is very basic terms... Magnetic energy and electric energy used to be seperate. Since they act is much the same way, and for the same reasons, is is now know as electromagnetic energy. This is the bare-bones answer. Magnets have an electromagnetic field of oppositely charged ends (the North and South poles). This field interacts with other fields. If the field ends are of the same polarity (charge)(N-N, S-S), they repel each other. If they are oppositely charged (N-S, S-N) they attract.
