As we all know, pot magnet is a magnet assembly that inserts a powerful sintered Ndfeb magnet into a durable steel housing or groove. Sometimes it is also called a pot, hence the name "pot" magnet. It is also known as a cup magnet or mounting magnet, fixed magnet. Permanent magnets are very brittle, easy to break, and have limited magnetic force. Powerful pot magnets can be a good solution to these problems. The steel housing provides a safe place for the inlaid powerful circular/rectangular permanent magnets, while the housing or pan provides a magnetic shield that concentrates the magnetic forces on only one face and enhances them. Most pot magnets can be heated to temperatures up to 80°C without losing their magnetization.
