how does a diode reduce electromagnetic field created at the household circuit breaker?

Question

i can purchase a copper diode that claims to provide protection against emf where electricity enters the house. advertising says it neutralizes energies. is this likely to be a true claim? thanks.

Answer 1

Sounds like a scam to me. A diode is a P-N semiconductor junction that allows current to flow only in one direction. It effectively acts as a short circuit, like a normal wire, when voltage is positive, and like an open circuit when voltage is negative. Regardless of how the diode is applied, you would need one heck of a diode to handle the standard 2 Amps of a household circuit. Besides, EM fields are not harmful to humans, so far as we can tell. Additionally, the 60Hz standard AC frequency does not interfere with any standard wireless appliances. So regardless, there is no need to "neutralize EM fields" in your home.
Edit - I noticed it was advertised as a "copper diode" which cannot exist (unless it is a Schottky diode, in which case the description is still misleading).

Answer 2

It does not.

Diode conducts one way and not the other. It has absolutely NOTHING to do with magnetic fields. Besides, magnetic field created around the circuit breakers are negligible. They are not harmful to anything what so ever.

What is "copper diode?" Copper is a conductor. Diodes are made out of semi-conductors. (P and N type)

You are either reading the materials incorrectly or someone is trying to deceive you.
