This is an example of the coil simulation, performed with QuickField software.
Axisymmetric problem of transient magnetics.
All dimensions are in millimeters.
Relative permeability of winding μ = 1;
Relative permeability of steel μ = 500;
Voltage U = 0.1 V.
DC voltage is applied to the coil. Calculate the switching current.
