Magnetic Product Description:

This magnet has a length of 20mm, a width of 12mm and a height of 5mm. It uses AMF Magnet part number 22021E.

Uses for our Rare Earth block magnets:

To join anything to anything else is a compromise or a transaction. Fabrications usually separate at the joint. Like all compromises and transactions, costs apply. The very first joining task, attaching sharpened stone fragments to the end of wooden spears, came with significant compromises or transaction costs.

The spears took longer to make and were heavier, you carried fewer of them. Heavier to throw, the hunter would have to get even closer to prey increasing the risk of flight or fight. If the stone tip uncoupled for any reason, a blunt timber rod remained. Useless for the rest of the hunt or against counter attack from injured prey. These transactional costs were paid in the hope stone tipped spears would result in better hunting.

The youngest members of the fastening family, magnets, are outperforming traditional fasteners like bolts, screws, rivets, nails and glues. The reasons are many. However, the main reason magnets will be soon crowned the master fasteners of the new world can be explained by one simple word. Plastics.

Plastics of all kinds, manufactured in all kinds of ways, including 3D printing, are proliferating in all industries, all across the world. The transaction costs or compromises of penetrative or adhesive fixing for plastic fabrications are too high. To fasten with magnetic bond however imposes no penalties. Secured with magnetic tape or placed into socket pockets of plastic fabrications (tools, toys and television news desks) for renewable, instinctive and intuitive release, magnets master the new paradigm.

Regularly used by the education sector and specialist design firms. A good all-purpose magnet with multiple applications.

Magnet purchase

The magnets were great, but not quite strong enough for my purpose. Maybe I will buy stronger ones next time :)

Service excellent !
