Product details

  • SKU 10040
  • Pull Force*

    The Pull Force listed for each magnet is based on lifting 10mm thick steel from a horizontal surface. Magnets on a vertical surface (of 10mm thick steel) are generally able to hold around only 30% of the pull force listed in the product description. This is due to the effects of gravity and the lack of friction between the surface and the shiny magnet. Read More

Ferrite Disc Magnet - 20mm x 3mm | Capped

Reliable, durable, and ready for everyday use, this Ferrite Disc Magnet with Protective Cap measures 20mm in diameter x 3mm in thickness and combines a high-quality ferrite permanent magnet with a durable protective cap. Designed to help safeguard contact surfaces while improving handling and appearance, this capped ferrite magnet is ideal for offices, warehouses, schools, workshops, retail displays, and general-purpose magnetic holding applications.

Manufactured from premium ferrite magnetic material, this magnet offers dependable magnetic performance along with excellent resistance to corrosion, oxidation, moisture, and demagnetisation. Unlike rare earth magnets, ferrite magnets require no protective coating, making them a low-maintenance and economical solution suitable for long-term indoor and outdoor use.

The protective cap helps reduce the risk of scratching delicate steel surfaces, provides a cleaner finished appearance, and makes the magnet easier to grip and remove. This makes capped ferrite magnets particularly suitable for noticeboards, whiteboards, planning boards, warehouse racking, signage, and display systems where magnets are frequently repositioned.

Magnetised through the 3mm thickness (axially magnetised), this magnet delivers a stable magnetic field across its working face while maintaining the durability and reliability ferrite magnets are known for.

Advantages of Capped Ferrite Magnets

The protective cap provides a more user-friendly magnet by improving grip, reducing direct contact between the magnet and mounting surface, and helping to minimise scratches on painted or coated steel surfaces. This makes capped magnets ideal for applications where magnets are regularly moved or handled.

Suitable For

  • Offices and classrooms
  • Warehouses and factories
  • Retail environments
  • Manufacturing facilities
  • DIY and hobby projects
  • Educational demonstrations
  • Display systems
  • General magnetic organisation

Please Note

Ferrite magnets are hard and durable but can be brittle if subjected to impact. While ferrite magnets generally provide lower magnetic strength than neodymium magnets, they offer excellent corrosion resistance, long service life, and exceptional value. Holding strength will vary depending on the thickness, cleanliness, and condition of the steel surface. Keep away from children, pacemakers, sensitive electronic devices, and magnetic storage media.
