Abstract

Improvements in the magnets usable especially in the magnetic closures, characterized in that in closures made of TICONAL, or of a material that or of a material that has an analogous demagnetization curve, and having a length L comprised between ** (see formula) * *, the closure is combined with two pole pieces arranged so that they constitute a double air gap, one of which is fixed and the other variable, and because the dimensions of the fixed air gap satisfy the following conditions: **(See formula)** ** (see formula) ** in which: S represents the contact surface of the magnet with the pole pieces, L the length of the magnet between the contact surface with the pole pieces, and the width (or sum of widths) of the fixed air gap (s), s'' the surface of each of the parts of the pole pieces that make up the fixed air gap.
