Use Nd-Fe-B as the core, which makes it small volume, light weight and strong magnetism. Remanence is almost zero with optimize-designed magnetism distribution, and the safe coefficient of lifter is 3.5 times. The

"V" design on subface makes it easier to lift up round and flat steel.

Magnetism keep permanent, safe and convenient. It can operation in the field, and widely used to lift and transport the steel and iron for factories.
