A conducting rod ab makes contact with metal rails as shown in figure. The apparatus is in a uniform magnetic field B=1.2 T, Perpendicular to the plane of the "loop" and directed into the page. Calculate the magnetic flux through this loop with fixed dimensions for width (W) and length (L) given as in the figure. Now the rod ab is pulled to the right. Find the magnitude of the emf induced in the loop when the rod is moving to the right with a speed of v=12.0 m/s If the resistance of the entire circuit loop is R= 2.25 ?what is the magnitude and direction (clockwise or counter-clockwise) of the current induced in the loop?

Explanation / Answer

A. flux = B.A.cos/thetha

= 1.2 *0.20*0.50*cos0

= 0.12 Webre

B. emf = B*l*v

= 1.2*0.20 *12

= 2.88 Volt

C. I = V/R

= 2.88/2.25

= 1.28 Amp

D. magnitude of force = i*L*B

= 1.28*0.20*1.2

= 0.3072 N
