10mm (0.39") thick rectangular magnets are extremely popular because despite their compact size they still generate an impressive magnetic pull. In this section you will find both 10mm (0.39") thick rectangular neodymium and ceramic magnets. The largest neodymium magnets in this section can produce an incredible pull of 30kg (66.14lbs)and are used in specialist, large-scale engineering while the large ceramic magnets which aren't as strong as neodymium magnets are commonly used in manufacturing and conveyor systems.
