Question

Part B Item 3 Find the fluxP through the loop Express your answer in terms of z, y, and B Learning Goal To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as Submit My Answers Give Up where E is the emf induced in a closed loop, and Part C Figure 1 If the magnetic field steadily decreases from B to zero during a time interval t, what is the magnitude & of the induced emf? of 1 Express your answer in terms of z, y, B, and t Submit Hints My Answers Give Up Review Part Part D If the magnetic field steadily decreases from B to zero during a time interval t, what is the magnitude I of the induced current? Express your answer in terms of z, y, B, t, and the resistance R of the wire

Explanation / Answer

Here.

part B)

flux through the loop = magnetic field * area of the loop

flux through the loop = B * x * y

part C)

magnitude of emf induced = change in magnetic flux/time

magnitude of emf induced = B*x*y/t

the magnitude of emf induced is B*x*y/t

part D)

let the resistance of wire is R

induced current = induced emf/R

induced current = (B*x * y)/(t * R)

part E)

Using lenz's law

the direction of induced current is counterclockwise
