Correctly select the current density of the induction coil to achieve the purpose of energy saving

Apabila arus induktor bagi relau pemanasan induksi is constant, the cross-sectional size of the pure copper tube of the induction coil should be selected to control the current density within a certain range. The current density increases, the power loss of the induction coil increases, and the electrical efficiency of the inductor decreases. Of course, the cross-sectional size of the pure copper tube of the induction coil is also determined by the number of turns of the induction coil and the geometric size of the inductor.
