These magnets have properties very superior to the traditional ones, being at the moment the most powerful magnets of the market. Neodymium magnets are magnetic elements with greater remanence and high coercivity. Thanks to its magnetic properties, the neodymium magnet is the most powerful on the market, being the most used in the industrial sector. Neodymium magnets in equal size with other magnets, such as ferrite, are stronger, even in some cases, being smaller, can withstand more strength.
