coil transient current, solenoid switching on, transient current in solenoid
This is an example of the coil simulation, performed with QuickField software.
Axisymmetric problem of transient magnetics.
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.
