Ferrite disc magnet Ø 40 mm, h. 8 mm, strength 1.4 kg

Ferrite magnetic discs are classified as permanent ceramic magnets. They are highly resistant to corrosion, moisture, and temperatures up to 250 °C, making them suitable for environments where standard magnets would require a protective surface coating. A magnetic disc with a diameter of 40 mm and a height of 8 mm has a magnetic pull of approximately 1.4 kg, a weight of 45 g, and axial magnetisation Y30.

The larger 40 mm diameter creates a substantial contact area, which helps to distribute the magnetic force evenly across a larger contact point with a steel surface. The 8 mm height provides sufficient ferrite material for a reliable holding force. The ceramic material does not corrode, so the magnet can also be used in outdoor environments or in places with higher air humidity. The ferrite magnet requires no surface treatment and retains its properties even during long-term use.

The larger dimensions make this disc more suitable for technical and industrial applications than for small hobby projects. This large magnet is used in the production of magnetic holders, separation devices, loudspeakers, electric motors, or various manufacturing equipment.

Large ferrite disc magnets are suitable for:

• magnetic holders and fixtures,
• the production of loudspeakers and electric motors,
• magnetic separators and technical equipment,
• assembly and production fixtures,
• industrial and electrical engineering applications,
• outdoor use, as they are corrosion-resistant,
• collecting metal components in workshops,
• long-term technical use,
• magnetic joints with a larger contact area.

You can glue the magnet using magnet glue.

Warning: Do not bring weaker ferrite magnets close to strong neodymium magnets, as this may lead to the demagnetisation of the ferrite magnet.

The ferrite magnet has axial magnetisation Y30 with poles on opposite flat surfaces.

A large contact area and moisture resistance make this disc a suitable component for technical equipment and industrial fixtures. If you are looking for a magnet for long-term operation without the risk of corrosion, this magnet will be a good choice for you.
