Ferrite Φ20×5 (anisotropic) 10 pieces FE005 1 bag (10 pieces)

It has the best cost performance. This is the type of black magnet that you typically see and is used for a wide range of purposes. Although its magnetic properties do not compare favorably with those of rare earth magnets, its high coercive force makes it difficult to lose magnetism and extremely stable. There are anisotropic and isotropic magnets, and anisotropic magnets have a stronger magnetic force than isotropic magnets. It has low mechanical strength and is prone to breaking like ceramics. It is resistant to rust, so surface treatment is usually not required. Shape: Round Size: diameter 20mm x thickness 5mm Material: Anisotropic ferrite Surface treatment: N pole white mark Magnetization pattern: Thickness direction magnetization RoHS2 (EU)2015/863 compliant [About RoHS]
