A Pot Magnet is a kind of magnet wrapped in a steel shell and shaped like a pot, also called a magnetic component. Through the design of the magnetic circuit, the steel shell will increase its tensile force.
The magnetic permeability of the pot shell is much higher than that of air, so the magnetic lines of force in the steel shell are easier to pass than those in the air. The guidance of the magnetic circuit makes the lines of magnetic force focus on the work surface. After being in contact with the working surface, the magnetic field lines of the pot-shaped magnet are much more focused than the simple magnet, so its pulling force is also many times stronger than that of the simple magnet.
The application range of Pot Magnet is suction, doorstop, traction light, magnetic clamp, and so on.
