How it can be magnetized

Type A - AXIAL
ONE FACE NORTH AND ONE FACE SOUTH
Max width: 200 mm.

This type of magnetization can be used, for istance, in electronics for closing contacts (Reed e Hall).

It can also be efficiently used whenever repulsive forces have to be exerted on very small pieces that cannot be magnetized using the other 2 types mentioned below, or when it is necessary to channel all the magnetic flux into the metal pole pieces.
Type B - TWO POLES
EQUAL MAGNETIC FORCE ON BOTH SURFACES
Width: from 10 to 70 mm.

We recommend you use this kind of magnetization when there are gaps present (material located between magnet and the iron piece to which it has to adhere to).
Type C/M - MULTIPOLES
EQUAL MAGNETIC FORCE ON BOTH FACES
POLE PITCH: 7 mm.
Width: from. 23 to 70 mm.
 
Type C - MULTIPOLES ON ONE FACES
THE LEAST MAGNETIZED SURFACE IS LIGHTLY ENGRAVED OR MARKED WITH A FELT TIP.

POLE PITCH: 7 mm.
Width: up to 450 mm.

The magnetization of the C/M and C types is more sensitive to gaps than that of the B type.
It is recommended when gaps are very low and when bigger sizes than those of the B type are needed.

The magnetic force of the B and C/M types can be remarkably increased by putting an iron plate of about 1 mm if thickness on a surface, as it can be inferred by the holding force charts here below.

For the C type, the iron plate has to be put on the engraves or felt-tip marked surface.
