- 50mm x 50mm x 20mm
- Each magnet's north and south poles are on opposite 50mm x 50mm square faces
- Each magnet can support a steel weight of up to 6.8kg 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 like this particular variety, are commonly used in the construction of wind turbines.
