Inductive coupling & wireless power transmission

  1. Sep 29, 2011 #1
    I'm considering a very simple method of powering a small electronic device from a typical current carrying outlet. I'm trying to make a theoretical prediction to the amount of current I could generate using magnetic induction.

    I have a straight current wire carrying an alternating current and I put a single loop of wire in around the it, in the perpendicular direction. I need to find out the amount of induced current generated in the loop.

    I know I need to use Faraday's law but the AC part is confusing me. All the examples like this I can find involve two coils near each other like in a transformer. I have a straight wire with AC to induce current in a coil.

    If anyone could help me out to how I would start this calculation that would be great

    kind of like in the first picture here:
