Electricity production from a magnetic field.

SUMMARY

This discussion centers on the feasibility of recharging a device using the magnetic field generated by electricity flowing through a 15-2 Romex-type power wire. It confirms that tapping into the magnetic field is possible if the user is responsible for the electricity bill. However, challenges arise in effectively coupling to the wire pair due to their close spacing, which is designed to minimize stray magnetic fields. The conversation emphasizes the importance of understanding energy requirements for successful power extraction.

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...
thanx

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?
