Question

(11%) Problem 2 . A rod AB with length L = 0.1 75 m is lying on a rectangular conducting loop of zero resistance in a magnetic field as shown in the figure. The magnetic field has a constant magnitude B-0.45 T. The rod is moving to the right with speed v .61 m/s. The resistance on AB is R = 140 . Randomized Variables 0.175 m B 0.45 T v 0.61 m/s R= 140 x@f x@f x x Otheexpertta.com u ee 10% Part (a) Express the change of the magnetic flux going through the loop 1, dd, in terms of B. v, L and 4. " 10% Part (b) Express the magnitudc of the average emf induced in loop 1, 1, in terms of B, L and v. I

Explanation / Answer

(I) Induced Current = Induced emf / Resistance of rod

I = El / R

(j) El = B.L.V = .45 x .175 x .61 = 0.0480375 V

I = E/R

I = 0.0480375 / 140

I = 3.43 x 10^-4 A
