Round Magnets（Attraction Froce (Range)：20.1 to 30.0）

Round magnets are products used to stick items to magnetic objects made of ferrous metals. Besides sticking objects together, they are also used for applications such as magnetism testing and in parts requiring magnetic attraction. Magnets are available in types such as neodymium, ferrite, cobalt and alnico. The magnetic force of neodymium magnets is one of the strongest among the available magnet products. Neodymium magnets are used in a wide range of applications. Ferrite magnets have a weak magnetic force but relatively high retentivity. Cobalt magnets are officially known as samarium-cobalt magnets. They are known for their resistance to rust and high temperatures. Alnico magnets have superior temperature resistance properties and outstanding mechanical strength. The high retentivity of industrial magnets enables even small models to emit powerful magnetic fields. Using a magnet at temperatures above its maximum operating temperature creates the risk of weakening its magnetic force.
