In a bar magnet, strength of the north pole is _______ the strength of the south pole.
greater than

equal to
The strength of the south pole of a magnet is greater than the strength of its north pole.
is it possible to have a bar magnet in which magnetic strength of north pole is different from south pole.? suppose 2 bar magnet of same strength and same length are connected in series such that north pole is connected to south pole and south to north. can we replace their combination by a bar magnet whose centre coincides and strength becomes double?
