60mm x 20mm x 15mm Each magnet's north and south poles are on opposite 50mm x 19mm rectangular faces Each magnet can support 4.8kg pull vertically from the magnetic face when in flush contact with a mild steel surface of equal thickness Resistant to demagnetisation and corrosion without any extra coating Also known as ceramic magnets, ferrite magnets offer excellent value for money when pull strength is not the most important factor. They have a high resistance to corrosion and demagnetisation, can operate in temperatures up to 180 degrees Celsius and are commonly used in conveyor systems, switches and manufacturing.
