This is a bar permanent magnet which made of sintered ferrite. The specific size is 60mm in length, 20mm in width, 10mm in thickness, this magnet has no coating, the color is the black of ferrite itself. The grade of this sample is Y30BH, and the magnetization method chosen is thickness, but other direction. Ferrite has good demagnetization and corrosion resistance. Magnetic strength is more than 1110 Gauss.
