Which option most accurately defines Faraday's law? Any change in the electric field over a conductor will produce an magnetic field inside a conductor. The voltage generated in a coil is inversely proportional to the cross-sectional area of the coils loops. Any change in the magnetic field over a conductor will produce an electromotive force and electric current in the conductor. The voltage generated in a coil is inversely proportional to the number of electrons in the loop.
