Description Material NdFeB Shape Rod Diameter 5 mm Height 25 mm Tolerance /- 0.1 mm Direction of magnetisation axial (parallel to height) Coating Nickel-plated (Ni-Cu-Ni) Magnetisation N45 Strength approx. 1,1 kg (approx. 10,8 N) Max. working temperature 80°C Weight 3,7 g Rod magnets have a classic cylindrical design that many of us remember from school. Their diameter is generally smaller than their height, however, we also depict magnets that have the same diameter and height.
