20x10x5mm is supplied as a standard size for rectangular (block) neodymium magnets, which can be found on many magnet shops. Depending on grade, rectangular neodymium block magnets of 20x10x5mm produce 11-16.3 LB magnetic force, the magnetic poles are on the sides of 20x10mm, and they are usually plated with nickel. Countersunk holes can be customized on 20x10x5mm neodymium block magnets. (To know more about customization: custom neodymium magnets) The grade of N52 is needed for the strongest pulling force, and the grade of N35 is needed for the cheapest price. We deliver all grades of neodymium magnet 20x10x5mm with plastic spacers.
