This magnet has a length and width of 20mm and a height of 12mm. It has a magnetic flux of 4606 Gauss and a pull force of 14.8kg against 5mm mild steel. It uses AMF magnet part number 22015.
Designers and their clients have a growing need for products that are easy to service, clean and dismantle for transportation or storage.
Magnets bond to metal or each other without penetrating the host materials and have little or no effect on the structural integrity of the surface they adhere to. Nails, pins, rivets, screws and bolts, by nature and design, pierce surfaces. Glues deface plastics when dismantled. Penetration weakens or fatigues plastics at the point of entry and facilitates moisture access as well as compromising the uniformity and integral strength of plastic materials. This popular magnet is used by boat manufacturers, industrial part suppliers, shopfitters, material handling companies and is regularly purchased by a V8 Supercar race engineering team who require the unique instant hold, and instant release qualities that magnets of the correct size and strength provide.
Small and compact in size this magnet is still powerful and should be handled with care!
I purchased these magnets for use in an internal training course for work to show how metals behave in the presence of a magnetic field. These magnets are small enough to drop through a roll of aluminium foil to demonstrate the bahaviour.
I used the magnet to fix my shonky oven door
I ride my track bicycle on rollers for training purposes. While rollers give a very realistic riding experience, and are good for pedaling technique, they don't provide enough resistance for building muscle power. One ends up maxing out leg speed (this happens for me at 160-170 rpm) before running out of strength.
Mounting a magnet very close (2mm or less) to the aluminium roller surface generates eddy currents in the roller when it spins. The eddy currents generate an electric field that interacts with the block magnet's magnetic field to generate a force that acts to slow the rollers down, converting the rider's effort into heat due to electrical resistance to the eddy current. The force provided increases linearly with the roller speed, so the faster one rides, the more resistance one feels.
The three Neodymium block magnets I purchased from AMF Magnetics currently provide my rollers with over 900W of resistance @ 150rpm which is all my current fitness and strength can handle. With consistent training, I hope to need another magne

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
