Coil with user-defined voltage

I need to find magnetic field, as a function of time, in the system of coils where voltage is a user-defined function of time. Can I use CA/DC, and where I set the dependence V(t).

Thank you

Hi Larisa,
The coil can be excited with voltage input as a function of time as shown in the attached model.
Within Multi-Turn Coil 1 -> Multi-Turn Coil -> Coil excitation (Voltage) -> Voltage = 1[V]*sin(2*pi*50[Hz]*t).
The same excitation can also be used for Single Turn Coil as well.
