Can a Copper Coil Harvest Power from Power Lines for an FM Radio Receiver?

Click For Summary
SUMMARY

This discussion centers on the feasibility of using a copper coil as an antenna to harvest power from electromagnetic fields generated by power lines for an FM radio receiver. It confirms that a simple copper coil can serve as both the electromagnetic field receiving antenna and the RF antenna, although the legality of harvesting power from electric company lines is emphasized. The conversation highlights the importance of understanding the legal implications of power harvesting and suggests that household power lines may be a more viable option.

PREREQUISITES
  • Understanding of electromagnetic fields and their properties
  • Basic knowledge of FM radio receiver components
  • Familiarity with antenna design principles
  • Awareness of legal regulations regarding power harvesting

I had an idea of building an FM receiver that is powered from the electromagnetic fields generated by power-lines.
My question is , how can I make the electromagnetic field receiving antenna? Will a simple copper coil work? If so, can the same coil be used as the RF antenna or will that have to be separate?

Harvesting unmetered power from electric company power lines is illegal.
But perhaps you are harvesting power from your household power lines.
