Product Description:
Magnetic Cups are made from neodymium magnets, the world's strongest magnets. Neodymium magnetic cups provide much stronger holding power than ceramic cup magnets.
This handy and useful neodymium magnetic cup has a strong magnet embedded inside a Nickel coated steel cup to offer the maximum gripping power. The steel cup offers protection for the magnet and concentrates the magnetic force on the magnet surface.The cup magnet has a countersunk center hole that is perfect for mounting with a flat head screw or bolt.
Neodymium Magnetic Cups Size: 18.9 mm Diameter x 7 mm thick with 8.5mmx4.5mm counter sink hole

NdFeB, the third generation of rare-earth permanent magnet, has high remanence, high coercive force, high-energy product and high performance/cost ratio.
Neodymium Magnets are easily formed into various sizes and widely used in many fields such as magnets for aviation, electronics, instruments, meters, machine and medical instruments. Neodymium metal is used extensively to produce Nd-Fe-B magnets, which have energy densities as high as 27 to 35 million gauss oersteds.
They are the most compact magnets commercially available. It is especially suitable for the development of magnets for high-performance, compact and light products.
