Magnetic Pot Round Base Magnet are ceramic or neodymium magnets clad with a steel cup. Magnetic strength can be multiplied with the block of the steel cup, These magnets are often found in applications requiring a strong holding device or the ability to attach a post or hook to hang inspection equipment, indicator gauges, lamps, signs, antennas and other items.
The steel cup outside the magnet will protect the magnet from the direct impact when meet other iron or steel things, also, these steel cup will protect the magnet form corrosion of the outdoor humid environment.
The Rubber Magnet Base is made of small Neodymium Magnet discs, steel,and rubber, these magnet discs will effect the magnetic loop with each other and spread out, the steel plate will block and enlarge the magnetism of these magnet discs,the rubber that cover the magnets and steel plate will protect the magnet from impact and corrosion. rubber magnet base is a amazing invent with great help.
Magnetic Pot Magnet round base are very long of using life, they can keep their magnetism for more than 10 years in the outdoor humid hot environment. Over 15 years in the indoor environment.
