the force will be stronger grip attached

general injection molding industry uses the most is made of ferrite permanent magnet material, the surface magnetic field strength of about 2000 gauss; the food and chemical industries with magnetic grille, magnet tube the use of rare earth neodymium iron-boron magnet, the surface magnetic field strength in 6000 to 12,000 gauss, the relative magnetic ferrite grill a lot stronger during use, size adsorption iron impurities will be more small, rare earth permanent magnets the force will be stronger grip attached
