Shallow Pot Magnet / with Steel Cover

Shallow Pot Magnet / with Steel Cover

The principle of this pot magnet is to glue one piece of solid disc magnet, either NdFeB or Ferrite, into the steel housing. Then, depending on customer's applicational requirement a cover made of stainless steel is available.

FAQs about Shallow Pot Magnet / with Steel Cover

  • What is the strongest magnet?

    The strongest permanent magnets in the world are neodymium (Nd) magnets, they are magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

  • What is a cup magnet?

    Cup magnets are magnets inset into steel cups that assist in mounting and increase their holding force. They are commonly used in holding applications where they are attached to a surface with a countersunk screw.

  • What is a pot magnet?

    A pot magnet is a permanent magnet encased in a steel shell, which is sometimes called a pot, hence the name 'pot' magnet. A permanent magnet emits a magnetic field without the need for any electricity. Pot magnets are often used as magnetic bases and magnetic holders for large supermarket ceiling signs.

  • How does a pot magnet work?

    A pot magnet works by attaching itself to ferromagnetic materials with the help of its magnetic field, or to non-ferromagnetic materials with the help of fittings (such as studs and threaded holes) on the top of its steel shell. ... The larger the pull force of the pot magnet, the more material it can attract.

Technical Advantages

Higher Force

Comparing with its peers that have either a through hole or countersunk hole, these flat pot magnets have even higher magnetic force because of their larger contact surface.  


Durable

Filling material is used between steel pot and magnet so that dirt and dust are always kept outside of the internal structure and, subsequently, longer durability of these pot magnets can be obtained.


Steel Cover

Not having a mounting component like a screw hole or thread bolt, the shallow pot magnet is usually used together with adhesive tape to fix itself in place with magnetic side facing outwards for holding.
