Need help with all parts please!

(3%) Problem 18: A conducting rod of length L 0.045 m is lying on a rectangular wire as shown in the figure. A constant magnetic field with magnitude B- 0.45 T pointing into the paper is in the region. The rod is pulled to the right by an external force, and moves with constant speed v 0.065 m/s. The resistance in the wire is R 105 S2.

Explanation / Answer

(A) flux = B.A

= B a L

(B) rate of change of magnetic flux = [d(flux) / dt ] deltaT

= B L da/dt deltat

= B L v deltat

(C) e = rate of change of magnetic flux

e = B L v

(D) e = 0.45 x 0.045 x 0.065

e = 1.1316 x 10^-3 Volt

(E) I = e / R = B L v / R

(F) I = 12.5 x 10^-6 A

(g) counterclockwise direction
