7. Faraday’s Law “A coil of wire experiences an electro- motive force that is proportional to the rate of change of the magnetic flux passing through the loop.” Magnetic flux is the product of the magnetic field strength times the area it passes through projected onto the field direction (just like solar flux on a panel).
