Extra strong, heat-resistant block magnets. 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.
Block Magnets – Holding forces are measured on steel plates (constructional steel of thickness min. 1 cm). Other metallic bonding surfaces or other influences (air humidity, room temperature, vertical position, dirt or dust) might reduce holding force. All declarations are average values.
