Electricity production from a magnetic field.

  1. Sep 25, 2012 #1
    Is it possible to recharge a device, say of 15-2by converting the magnetic field is produced by electricity flow through any random wire anywhere?

    This is for an important exhibition and so i request an in depth answer which helps me figure out the hows and whats....

    If it is a "random wire" where you are paying the electricity bill yourself for the power being transmitted through the wire pair, then it should be okay.

    You are left with the problem of how to couple well to the wire pair, since power wire pairs are generally spaced closely together to minimize the stray magnetic field that is produced. The 15-2 Romex-type power wire pair has a spacing that is fairly close together. You could clamp onto the 15-2 and tap a small amount of power, though. How much energy do you need?
