Which pole of a magnet should I use?

Both the north pole or south pole of a magnet are equal in holding power and both will stick equally well to magnet receptive material such as steel, iron or our Flexometal sheet. 

The like poles of two magnets (e.g. north facing north or south facing south) will always repel each other while opposite poles (e.g. north facing south or south facing north) will always attract. We supply self-adhesive and countersunk magnets with either pole on the magnetic face so that it is possible to pair them up so that they will hold together – north facing south and visa versa.
