According to Faradays law , a changing magnetic field on a conductor induses current in the conductor through mutual induction.
How is electricity passed through a wire?
A wire contains mobile electrons as majority charge carriers and holes as minority charge carriers when an emf or potential diffrence is provided , electrons flow in opposite direction with holes(convection current flow)
The ground wire should not be smaller than No 10 copper.
