These discreet, white ferrite hook magnets are great value for money and ideal for hanging signs and decorations from a steel ceiling and are commonly used in shops to suspend advertising signs. The ferrite magnets are sunken in to a steel shell meaning that the north pole is on the centre of the magnetic face and the south pole is on the outer edge around it. The steel pot increases the adhesive force of the magnets giving them an incredible hold for their size.
