Suppose the rectangular wire loop with a resistance of 2.5 enters the magnetic f

Question

Suppose the rectangular wire loop with a resistance of 2.5 enters the magnetic field as shown in the figure, moving to the right at 22 cm/s . (Figure 1)

Part A: What is the magnitude of the induced current?

Express your answer to one significant figure and include the appropriate units

Part B: What is the direction of the induced current?

Part C: Later the loop is fully in the field, still moving at 22 cm/s . What is the magnitude of the induced current?

Express your answer to one significant figure and include the appropriate units.

Part D: What is the direction of the induced current?

Part E: Eventually the loop begins to emerge from the field, still at 22 cm/s . What is the magnitude of the induced current?

Express your answer to one significant figure and include the appropriate units.

Part F: What is the direction of the induced current?

Explanation / Answer

(A) induced emf = B L v

= (0.85)(0.08)(0.22)

= 0.015 Volt

I = e / R = 5.98 x 10^-3 A Or 5.98 mA

(B) counterclockwise direction

(C) I = 0

(d) no direction

(e) I = 5.98 mA

(f) clockwise
