1. The magnetic circuit is designed by computer simulation, with large permeability and strong magnetic force.

2. The interior is cast with electrician special resin, self-cooling fully sealed structure, dustproof, rainproof and corrosion resistant.

3. The wave-fin heat sink greatly increases the heat dissipation area and effectively controls the temperature rise.

4. It can effectively absorb 0.1-50 kg of ferromagnetic substances mixed in non-magnetic materials.
