Pack of 4 N42 Neodymium arc magnets, each capable of supporting a 5kg pull vertically from the mag...Pack of 4 N42 Neodymium arc magnets, each capable of supporting a 5kg pull vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness. These magnets are commonly used in motors for both rotors and stators. They are magnetised with the north and south poles on opposite flat faces. Each magnet features a 90-degree curvature, with four magnets required to create a full circle. The specifications for each magnet are: 20mm outside radius, 12.5mm inner radius, 5mm thick. They have a premium coating of nickel, copper, and nickel for superior corrosion resistance and a smooth finish.
