Question

The figure shows a conducting loop of wire being pushed into a uniform magneti field coming out of the page with a magnitude of 0.75T. The loop of the wire has a total resistance of 10 Ohms. There is an applied force to the right edge of the loop pulling it into the uniform magnetic field (to the left with a constant speed of 10 m/s. (Not sure if this part is important but there is a width of the rectangle of 25cm). What is the magnitude of the applied force needed to push the conducting rod at the constant speed of 10 m/s? A. 0.0 N B. 3.9 B C. 3.6N D. 3.6*10^-2N

Explanation / Answer
