Ferrite block magnet 20 × 20 × 3 mm, strength 430 g

A ferrite block magnet has a lower magnetic force compared to neodymium magnets, but it resists corrosion, moisture and temperatures up to 250 °C. The block measuring 20 × 20 × 3 mm has a magnetic force of approximately 430 g, a weight of 5.8 g and a magnetization of Y30.

Ferrite magnets are suitable wherever a high holding force is not required. The dark grey ceramic material requires no surface treatment, does not rust and resists outdoor conditions. Thanks to this, it finds application not only indoors, but also outdoors or in humid environments.

This block magnet has compact dimensions, making it ideal primarily for light attachment of objects, production of magnetic aids or various hobby projects. The small thickness of 3 mm facilitates installation into products, wooden parts, plastic components or promotional items and magnets.

Ferrite magnets are suitable:

• for outdoor use, as they resist corrosion,
• for the production of simple magnets and promotional items,
• for DIY and model making projects,
• into wooden or plastic products as light magnetic closures,
• for magnetic boards and information systems,
• for school teaching, physics and electrical engineering experiments,
• for collecting small metal objects, such as pins or small screws,
• when making simple fixtures and aids for the workshop,
• for creative and artistic work.

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 magnetization of Y30, is axially magnetised, with the poles located on the opposite flat surfaces.

You can easily build a small block magnet into products, aids or promotional items where high magnetic force is not required.
