Faraday's Law: An induced EMF is generated when magnetic flux through a loop changes with time.
Lenz's Law: The induced current flows in a direction to oppose the change in magnetic flux (its own magnetic field opposes the cause).
Current Direction: Use the right-hand rule — curl fingers in the direction of current, thumb points in direction of magnetic field created by the coil.
