Explain why the focal length of a plane mirror is infinite, and explain what it means for the focal point to be at infinity.

Faraday’s Law of Induction Potential drop along the closed contour is minus the rate of change of magnetic flux. We can change the magnetic flux in several ways including changing the magnitude of the magnetic field, changing the area of the loop, or by changing the angle the loop with respect to the magnetic field 10 Lenz’s Law (1) Lenz’s Law defines a rule for determining the direction of an induced current in a loop An induced current will have a direction such that the magnetic field due to the induced current opposes the change in the magnetic flux that induces the current Meaning, if the flux increases, the induced B-field will be direc
