Diametrically

The diametral magnetization is the magnetization parallel to the diameter, for example in the case of disc and bar magnets as well as ring magnets. In this case, the magnetic poles are both on the straight faces of the magnets. It is contrary to the otherwise usual axial magnetization, i.e. opposite.

Diametral magnetization makes it possible, for example, to measure the revolutions on an axis without contact. The adhesive force also increases on level surfaces if the north and south poles are on the adhesive surface at the same time. With the same dimensions, more strongly adhering magnets are possible.
