I want to feed two flat circular coils with the same excitation current but with different phase, and as I can not change the phase of the excitation source of the coils. I am using the magnetics physics, frequency domain.

Orlando,

To feed two coils with the same current but with phase difference “theta”, define currents as following:

I0 for the first coil
I0*exp(j*theta) for the second coil

Regards,
Sergei
