Naturally occurring magnets can be found occasionally in nature. At first glance, magnetism and electricity seem to be totally independent quantities.
Electricity is related to the concept of charge.
Charges can be associated with specific particles such as protons and electrons and can have either positive or negative charge. These individual charged particles can be thought of as being sources of the Electric Field, or as poles from which the filed arises or disappears. Such single poles or charges are called mono poles. In the case of all magnets, both naturally occurring or man made, the field arises from two poles, or a dipole, one always of one type, usually called a north pole and the other the opposite type, usually called a south pole. Therefor, while electric charge can occur as a mono pole, singe positive or negative charge, magnetism is always a dipole.
