Opposes the effect which produces the induced current. A magnetic field goes through a loop of wire as shown below (x = intothe page). If the strength of the magnetic field is decreasing throughthe loop, what change will the loop produce according to Lenz's law?A. The loop will tend to restore the magnetic flux back to its initialvalue by increasing magnetic flux through the coil.B. The loop will tend to restore the magnetic flux back to its initialvalue by decreasing the magnetic flux through the coil.C. The loop will not react to this effect at all.
