Is the north pole of a magnet positive?

Magnetic north is negative and magnetic south is positive. The resulting magnetic field lines go from north to south. Mnemonic: north = negative.

The terms, 'positive' and 'negative', are generally applied to electric charges, not to magnetic poles. Having said that, 'magnetic therapists' use the terms 'positive' and 'negative' when referring to magnetic poles -however, their knowledge of magnetism appears very shaky!

Magnetic poles are normally identified as 'north' and 'south'. The 'direction' of a magnetic field, by convention, is the direction in which a compass needle would point when placed within that field -that is, from north to south.
