Question

(Figure 1) shows a 17-cm-diameter loop in three different magnetic fields. The loop's resistance is 0.90

Part A

For case (a), what is the induced emf?

Express your answer with the appropriate units.

E=1.1x10^-2V (correct answer)

Part B

For case (a), what is the induced current?

Express your answer with the appropriate units.

I= 1.3x10^-2 A (Correct answer)

Part C

For case (a), what is the direction of the current?

clockwise (correct answer)

Part D

For case (b), what is the induced emf?

Express your answer with the appropriate units.

E=___V

Part E

For case (b), what is the induced current?

Express your answer with the appropriate units.

I=___A

Part F

For case (b), what is the direction of the current?

1.) clockwise

2.) counterclockwise

3.) no current

(a) B increasing at 0.50 TVs at 0.50 T/s (c) B decreasing at 0.50 T/s

Explanation / Answer

The induced emf = -B/t*A

a) emf = 0.5T/s**0.085^2 = 0.0113V
i = V/R = 0.01134/0.9 = 0.0126A
the direction is clockwise

b) emf = 0.5T/s**0.085^2 = 0.0113V
i = V/R = 0.01134/0.9 = 0.0126A
the direction is clockwise

c) Flux is zero so emf = 0 and i = 0
