Question

Problem 21.14 Part A Part of a single rectangular loop of wire with dimensions shown in the (Figure 1) is situated inside a region of uniform magnetic field of 0.670 T . The total resistance of the loop is 0.230 Calculate the force required to pull the loop from the field (to the right) at a constant velocity of 2.00 m/s .Neglect gravity. Express your answer to three significant figures and include the appropriate units. Value Units Submit My Answers Give Up Figure 1 # of 1 0.350 m× × × × × 0.750 m

Explanation / Answer

E = B L v = 0.670 * 0.350 * 2 = 0.469 V

I = V / R = 0.469 / 0.230 = 2.04 A

Force required to pull = B I L = 0.670 * 2.04 * 0.350

Force required to pull = 0.478 N
