In this Exercise 6 we will explore laws critical to the study of electromagnetism. We will be using Simulation 3 (below) to explore how a moving magnet produces current in a nearby coil of wire. a. Magnetic field strength decreases as you get farther from the poles of the magnet. Does the flux through the face of the coil change as you move the magnet? Explain your answer. b. Why does the meter needle deflect? Is the deflection in accordance with Lenz’s Law? Justify your answer in terms of Lenz’s law and your above answers.

The self-inductance of the coil is defined as resistance offered by the coil for the change in the current in the same coil itself. Whenever the current flowing through the inductor changes, the coil will oppose the cause producing it. The mutual inductance of the coil is defined as whenever the current flowing in one of the coil changes an EMF is induced in the neighboring coil, according to this principle where the transformers are working. The transformers also have two windings that are close to each other.
