This has already been discussed on at least 3 different threads on this forum. It is a fake. The guy is a magician. He has a later video where he shows how it was done. There are no such things as monopole magnets! Think about it this way. Consider a garden hose where you put water into one end and out the other. Now think of the north pole as one end and the south pole as the other. Now can you have a single garden hose where you can put water into both ends or get water out of both ends. This is a very crude explanation for why there can't be any monopole magnets. One pole cannot exist without the other!
