Magnetic Holding Pad with through hole has one large rectangular bar magnet on its base.
This magnet has only one magnetic face, magnetised in the form of a multi-pole magnet.
This is where the magnetic face is magnetised in a striped pattern of alternating north and south poles e.g. north, south, north, south.

The through hole magnetic mounting pad requires multi-pole magnetisation due to the steel back plate preventing the magnetic field from escaping through the top of the magnetic mounting pad. Only one half the magnetic mounting pad needs to be magnetised so that it can attach to a ferromagnetic material. The other side is used to hold the sign with the help of the through holes.
