As we known the nomal magnet have two poles, the north and south, they are inseparable. Recently the newscientist report that with today technology the magnet pole can be cut into two pole or can be called monopole, the South pole and North pole.
Cutting a magnet in half only results in each piece developing its own north and south pole. That is true even if one disassembles a magnet all the way down to its individual atoms, since each behaves as a tiny bar magnet with two poles.
But physicists have theorized that magnetic monopolesMovie – individual north and south poles that are not bound in pairs and can move independently of one another – could form inside a crystalline material called spin ice.
