Ferrite block magnet 30 × 20 × 5 mm, 1.2 kg pull force

Although rectangular ferrite magnets have a lower magnetic force compared to neodymium magnets, they are resistant to corrosion, moisture, and temperatures up to 250 °C. A block measuring 30 × 20 × 5 mm has a magnetic pull of approximately 1.2 kg, a weight of 14 g, and a magnetization of Y30.

Ferrite magnets are used where maximum holding force is not required, but long-term functionality and resistance to the environment are essential. The ceramic material does not corrode without a surface finish, meaning the magnet functions perfectly in damp or outdoor environments.

The 30 × 20 mm size provides a larger contact area than smaller blocks, which is beneficial for manufacturing magnetic jigs, lightweight holders, or closures. The 5 mm thickness also makes it easier to embed the magnet into wooden, plastic, or metal structures.

Ferrite magnets are suitable:

• for outdoor use, as they resist corrosion,
• for manufacturing magnetic closures and latches,
• for workshop jigs and aids,
• for attaching lightweight objects,
• for producing magnetic boards and information systems,
• for model making and hobby projects,
• for school teaching, physics and electrical engineering experiments,
• for collecting small metal components,
• for creative and craft production.

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 a magnetisation of Y30 and is axially magnetised with poles on opposite flat surfaces.

The 30 × 20 × 5 mm ferrite block magnet is suitable for producing magnetic closures, workshop jigs, and anywhere where moisture resistance and long-term functionality are important.
