The Gauss value of ceramic ferrites (generally referring to sintered ferrite permanent magnets, such as strontium ferrite or barium ferrite) mainly depends on factors such as material grade, magnetization method, magnet shape and thickness, and surface measurement distance. Below is a reference table compiled by Xiao Fu for the Gauss values of various anisotropic ferrites. We hope you find it helpful.
