This cup manget is made of ceramic magnet or hard Ferrite magnet. The magnet is assembled inside a steel cup with a threaded stud as the fixture. It can be used as a holding magnet in various situations.
Since the magnet is fixed and glued inside the steel cup, it is much more durable than a regular magnet which may break under impact. So for the holding purposes, this assembly is more preferrable than a regular magnet.
Ceramic magnet is much cheaper than the neodymium magnet, this assembly provides you a much more economical solution than the neodymium cup magnets.
