The positive magnetic pole is the end of a magnet that faces north when it is free to rotate. There are several synonyms for this term, including the north pole, the north-seeking pole, and the attracting pole. Magnetic polarity has two possible states, either positive or negative, and these can be defined using the reference point of the earth's magnetic field. Positive magnetic poles will always be attracted to negative ones, and never to other positive ones. Magnetic fields are important in many areas, including motors, generators, and compasses, and understanding the terminology is essential for anyone working with electrical and electronic systems.
