Understanding Pot Magnets
Pot magnets are engineered to provide exceptional holding power in compact sizes. They consist of a magnet embedded in a housing that concentrates the magnetic force on one face, allowing for a strong grip on ferrous materials. This unique design makes pot magnets ideal for various applications, from industrial to everyday uses.
How Pot Magnets Work
The internal magnet within a pot magnet generates a magnetic field, which is focused and directed through the steel casing. When placed against a ferrous surface, the magnet creates a strong attraction due to the optimized magnetic circuit. This minimizes air gaps and maximizes contact, resulting in superior clamping force compared to traditional magnets.
