3Q) Analyze the relationship between flux produced by the moving coil and torque in a PMMC instrument.

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.

In a moving coil instrument, the coil has a length of 5 cm, a width of 4 cm and 80 turns. The magnetic flux, density in the air gap is 0.1 Wb/m², the hair spring provides a controlling torque of 0.5 × 10² Nm/ degree deflection of the coil. What current will be required to give a deflection of 600?

A P KN Refer to the figure. d₁ 0.9 m Force P is 60 kN and each force Q is 125 kN. Q KN B Add your answer Integer, decimal, or E notation allowed Q KN The diameter d₁ = 30 mm and diameter d₂ = 50 mm. d₂ 1.2 m What is the normal stress in rod BC in MPa? Round to the nearest integer and enter the magnitude only. C

a) State, in words, the two laws of electromagnetic induction. b) The diagram below illustrates the main components of one type of electromagnetic braking system. A metal disc is attached to the rotating axle of a vehicle. An electromagnet is mounted with its pole pieces placed either side of the rotating disc, but not touching it. When the brakes are applied, a direct current is passed through the coil of the electromagnet and the disc slows down. coil electromagnet pole piece axle metal disc

We will often use water as an analogy for electricity. This can help us to visualize circuits and current flow. However, this analogy doesn't always work. After learning about the laws attraction and magnetic induction, what are some ways that you can think of that demonstrate how the flow of electrical current is different than the flow of water?
