Neodymium Block Magnet Product Description:

These Rare Earth Neodymium Block Magnets, or Bar Magnets, have a centered countersunk hole designed for mounting on a surface. Strong Neodymium magnetic material allows for an impressive pull force of approximately 5.9kg. They are super strong considering their small size of 20mm x 12mm x 5mm. This permanent magnet is axially magnetised and the countersunk hole allows for the magnet to be installed on most surfaces.

AMF Magnetics uses high-quality Rare Earth Magnets for maximum strength. AMF offers bulk discounts for this product.

Uses for our Rare Earth Block Magnet with Countersunk Hole:

Many magnets, or magnetic devices, act as torque limiters. A torque limiter is a device that protects mechanical equipment from damage from any excessive mechanical force. Many of these devices use strong neodymium blocks because of their size to strength ratio. Often used in propeller assemblies or liquid pumps to regulate force through a watertight barrier. This method of transfer of force avoids the need for seals which fatigue easily.

This bar magnet is also used 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 allows for individual components to simply be re-attached by their owners.
