Simulation problem
Problem Type
Axisymmetric problem of transient magnetics.
Conductor diameter 1 mm, copper electric conductivity 56 MS/m;
Relative permeability of steel 500;
Voltage U = 0.1 V.
Calculate the current vs. time.
Since we do not know the time constant of the coil, we choose automatic time step option in problem properties.
