Hello guys,

I'm trying to simulate the induced voltage in a coil placed closer to a current-carrying conductor. I used a steel conductor path and an iron core (d=4cm) wound with copper windings (d=0.2mm). I was able to get the induced voltage by assigning a current excitation type to the coil. Then, I made the output current zero and the induced voltage results were recorded as open circuit voltage. 

Now I want to find the power output from the coil. So I tried using an external circuit to record the induced voltage and current from the coil. As per my knowledge, the output current will be maximum when the circuit resonates, hence I added a capacitor to match the inductance of the coil and attached another resistor with the same resistance as the coil. But now the direction of the induced voltage and current in the circuit are opposite. The direction of the current in the coil terminal was assigned according to Lenz's law. Your comments and thoughts about this is highly appreciated.

The primary setup is as below

Hello dinushaxdn,

      For generating, voltage direction should be opposite with current direction, to generate power. 

      When they are same direction, it means motoring. Thanks.
