Light is the result of an electron moving to a lower energy state, giving off a photon a particular wavelength in the electromagnetic spectrum. Current is the movement of electrons which induces a magnetic field. A magnetic field can create current by moving charges.
Is there a relation between the energy contained in light, and the energy of magnetic or electric field (as suggested by the name "electromagnetic spectrum")?
More questions:
Does a magnetic field exist anywhere there is a potential difference between positive and negative charges? If so, how is this different from an electrical field other than magnetic poles cannot be separated (unlike charged particles)?
Why does the magnetic field around a conductor form concentric circles when in the inverse situation (a charged particle entering a magnetic field) current spirals around the magnetic field needing an initial velocity in order to interact with the field?
Correct me if I'm wrong, I'm new to this, but very curious.
