Question

Exercise 29.22 A rectangular loop of wire with dimensions 1.69cm by 8.43cm and resistance 0.55 omega is being pulled to the right out of a region of uniform magnetic field. The magnetic field has magnitude 3.05T and is directed into the plane of the following figure(Figure 1) Part A At the instant when the speed of the loop is 3.00m/s and it is still partially in the field region. what is the magnitude of the force the magnetic field exert on the loop? Express your answer with the appropriate units. Part B What is the direction of the force the magnetic field exert on the loop? downward leftward upward rightward

Explanation / Answer

magnetic force F = l v B

F = 0.0169 * 3* 3.05

F = 0.154 N
