Performance magnet rods

Bar magnet work environment determines that it must have a certain degree of corrosion resistance, high temperature properties, and some situations require a relatively strong magnetization. By using different thicknesses of magnetic sheets can be different magnetic flux density. Select a different magnet can determine the maximum magnetic flux density and temperature resistance bar magnets, generally in order to achieve on a conventional 1 inch diameter magnet stick above the surface of 12,000 Gauss magnetic induction models need more than N40 NdFeB magnets. High temperature magnet bars at a temperature over 150 degrees or more general choice of samarium cobalt magnets. But do not choose large diameter samarium cobalt magnet, after a very high price SmCo
