Magnet

18mm (Diameter) x 6mm (Thickness) Neodymium Disc Strong Magnet is very useful for hanging or holding circular or disc shaped metal

20mm (Length) x 10mm (Width) x 1.5mm (Thickness) - Neodymium Block Strong Magnet is very useful for hanging or holding flat metal objects as well as a wide range of other magnetic applications. 

Ferrite Magnets are also known as Ceramic Magnets, Ceramic Ferrite Magnets, Feroba Magnets and Hard Ferrite Magnets. Ceramic Ferrite magnets are one of the most widely used permanent magnet materials in the world. Ferrite magnets are a low cost magnet material perfectly suited for higher volume production runs . They are termed ceramic due to their excellent electrical insulation ability. Ferrite magnets are superb in damp, wet or marine environments ? Ferrite magnets are corrosion free. Because the iron is already in a stable oxidized form in its structure, the iron cannot oxidize (?rust?) any further when in water.

20mm (Length) x 12mm (Width) x 6mm (Thickness) - Neodymium Block Strong Magnet is very useful for hanging or holding flat metal objects as well as a wide range of other magnetic applications. 

20mm (Diameter) x 3mm (Thickness) Neodymium Disc Strong Magnet is very useful for hanging or holding circular or disc shaped metal objects
