Method 1: the magnet with a thin wire hanging up, you can freely rotate in the horizontal plane, still will point to the north south direction, the north end of the N pole, the other end of the S pole

Methods: two magnet end and small needle N known polar repulsion is close to N, S is very attractive

2.Please forgive the magnet will have 2-3mm error
