Question

Suppose the rectangular wire loop with a resistance of 3.0? enters the magnetic field as shown in the figure, moving to the right at 35cm/s .

Part A

What is the magnitude of the induced current?

Part B

What is the direction of the induced current?

Part C

Later the loop is fully in the field, still moving at 35cm/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 35cm/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?

What is the direction of the induced current?

Explanation / Answer

induced EMF = -d(BA)/dt
dA/dt = .08*dl/dt = .08*v

E = -B*.08*v

= - .0238V

I = 7.933 mA

b)

Faraday
