A support plate by permanent magnets, which is essentially characterized by being a pair of parallel plates of sweet iron, of which the upper one has a series of equidistant gaps, having arranged in each hole a piece of sweet iron polar of great magnetic permeability, in which part slots have been made that increase the width of the air gap, said air gap being filled with a non-magnetic material.
