Occasionally a pamphlet for a salsa class might be tossed on a doorstop or stuck on a pole near a bus stop. There are two types of magnetic poles, called the north magnetic pole and south magnetic pole. The fixed point used as a reference in a system of polar coordinates. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded together, or more dense. The sum of these effects may cancel so that a given type of atom may not be a magnetic dipole.
