High current output

Hi everyone,

I am simulating a heat treatment with the induction heating module and I'm facing a problem concerning the single turn coil.
More specific I import as a coil excitation the a power of 640kW and I get a voltage of 120V and 10700A.
The voltage is fine, but the current is the double of what I expected. Any ideas of how can I fix this or check what's wrong?

Thank you!
Rosa
