Rare Earth magnets may be die pressed (with pressure being applied in one direction) or isostatically pressed (with equal pressure being applied in all directions). Isostatically pressed magnets achieve higher magnetic properties than die pressed magnets. The aligning magnetic field for die pressed magnets can be either parallel or perpendicular to the pressing direction. Magnets pressed with the aligning field perpendicular to the pressing direction achieve higher magnetic properties than the parallel pressed form.
Extra strong, heat-resistant (N45H) block magnets (12x7x2 mm). This magnets are often used by builders of model airplane who construct their own motors. The stronger the magnet, the smaller and lighter the motor can be designed. Heat-resistant up to 120 degrees.
Of course they can also be used as normal, extra-strong attachment magnets. Be careful when experimenting with these, as they can break easily due to their very thinness.
