nThank you for your support.I made a parallel with the simulation of the coil of a contactor, but in fact what I want to do are the following: ( The program is Ansoft Maxwell 14.0)n1) To supply the coil with a pulse current of 10 ms, with a current density that can reach 100A / mm2n2) To see the value of magnetic induction in the moving rod and the route of the field linesn3)To see when moving the coil the movement of the rod, possibly what force appears, graphically with heat.nI put below a picture with the section of a solenoid.Basically, when I supply the coil, I want the movable rod to move to the left 5mm and close a contact.nn
