Magnet Dimensions

Magnetic Product Description:

These Rare Earth Countersunk Magnets are essentially rare earth block magnets with centered hole, designed for mounting on a surface. They have an impressive pull force of approximately 5.9kg considering their small size of 20mm x 12mm x 5mm. They are axially magnetised and the centered hole allows for the magnet to be installed on most surfaces.

Uses for our rare earth block magnets:

Many magnets, or magnetic devices, act as torque limiters (A device that protects mechanical equipment from damage from excessive mechanical force. Magnetic bearings or magnetic couplings, many using neodymium blocks because of their size to strength ratio, are assemblies whose magnets relate in a manner that transfers or translates (electrical to mechanical) force, even through a barrier or screen. This sophisticated modern magnetic technology is often deployed in propeller assemblies or liquid pumps, mediating or regulating force through a watertight barrier separating wet and dry environments. This method of transfer of force avoids the need for seals which fatigue easily.

As a precaution on jewellery like necklaces and bracelets or earrings, magnetic clasps protect both the wearer and the precious material in the event of excessive force by uncoupling. This pre-determined, quit the grip, is determined by the jeweller. Once the excessive force event has passed, individual components are simply re-attached, click, stick and tick, by their owners.

    Life is about what you see.
    So hang is when u can
    Do not hide it
    Hang it on a magnet is cheaper than looking
    And finding after you bought a new thing.
