Q1 (a) List FOUR (4) basic principles for the operation of electrical machines.

6 What is the SI unit of a. magnetic flux b. magnetic flux density c. magnetic field intensity d. magnetomotive force

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.

UPVOTE WILL BE GIVEN. PLEASE WRITE THE COMPLETE SOLUTIONS LEGIBLY. NO LONG EXPLANATIONS NEEDED. ANSWER IN 2 DECIMAL PLACES.
