Wire cutting iron-silicon magnetic ring

A linear cutting iron-silicon magnetic ring comprises a magnetic ring assembly, magnetic ring buckle baffles and a through hole, the bottom end of the magnetic ring assembly is sleeved with a lower insulation cover shell, the top end of the magnetic ring assembly is sleeved with an upper insulation cover shell, and the magnetic ring buckle baffles are clamped to the magnetic ring assembly, the lower insulation cover shell and the upper insulation cover shell; the magnetic ring assembly comprises an integral magnetic ring, blending heat dissipation type silica gel, a semi-magnetic ring and a cutting face, the semi-magnetic ring is fixed to the top end of the integral magnetic ring, and the cutting face is arranged at the bottom end of the semi-magnetic ring. The heat dissipation type insulating silica gel added between the magnetic rings is beneficial to protecting saturation generated by high temperature of a circuit and also has a buffering effect, and when a wire with a relatively large diameter is wound, t
