Magnetic Holding Pots are made of permanent magnets assembled inside steel cups. Most of the round magnetic bases use either neodymium rare earth magnets or ceramic magnets. AlNiCo pot magnets can be found but SmCo magnet is rarely used. The benefits of the cup magnets are strength and durability. The holding strength of the round base magnets is much more powerful than the magnets built in the same round base magnets since the magnetic circuit design. The steel cups protect the magnets from direct hit so to have a much longer service life. Magnetop Magnetics carries a very wide selection of cup magnets for your favorite project.
Channel magnets are called that because they usually fit in the small recession or channel on the edge of a cabinet door. These handy cabinet magnets replace the old fashioned door latches of the past. Neodymium cabinet magnets are of course very strong and should be used for cabinets in motorhomes, boats and recreational vehicles when the doors must stay latched in a moving vehicle. The ceramic cabinet magnets are typically used in the home where there is no movement and the items behind the doors weigh less.
Both pot and channel magnets come with countersunk holes so that the screws used to anchor the channel magnets to the wood, plastic or metal lay flat and even with the surface of the cabinet magnet.
