Pot magnets, also known as cup magnets, are a type of permanent magnet encased in a metal 'pot' or cup. Here are some advantages and applications of pot magnets:
Advantages
Increased Holding Power: The metal pot enhances the magnetic force by redirecting the magnetic field from the back side of the magnet to the open side, which increases the holding force provided by the magnet on the open side.
Protective Covering: The metal pot not only enhances the magnet's power but also protects the magnet from damage. It reduces chipping or cracking of the brittle magnet material, such as neodymium.
Versatility in Mounting: Pot magnets often include a threaded hole, a hook, or an eyelet on the non-magnetic face, which allows for easy attachment with screws or hooks, making them highly versatile for various mounting options.
Compact Size: These magnets provide strong magnetic strength in a compact design, which is advantageous in applications where space is limited.
Resistance to Demagnetization: The casing helps shield the magnetic material from external magnetic fields that might otherwise demagnetize the magnet.
