A Conducting Rod Whose Length Is ℓ = 25 Cm $\vec { B }$

Multiple Choice

A conducting rod whose length is ℓ = 25 cm is placed on a U-shaped metal wire that is connected to a lightbulb having a resistance of 8.0 Ω as shown in the figure.The wire and the rod are in the plane of the page.A constant uniform $\vec { B }$ field of 0.40 T in magnitude is applied perpendicular to and out of the paper.An external applied force moves the rod to the left with a constant speed of 12 m/s.What are the magnitude and direction of the induced current in the circuit?

A) 150 mA clockwise
B) 150 mA counterclockwise
C) 34 mA counterclockwise
D) 34 mA clockwise
E) 100 mA clockwise
