Q. A coil of 100 turns kept in magnetic field B- 0.2T, carries a current of 2A as shown in figure. Torque on coil and which side of coil comes out from the plane of the paper :- (1) 0.16 N-m, BC side comes out from plane of paper (2) 0.16 N-m, AD side comes out from plane of paper (3) 0.32 N, BC side comes out from plane of paper (4) 0.32 N, AD side comes out from plane of paper Share with your friends Share 18 Pintu B. answered this Dear Student , Here in this case from the given data we can write that , Torque=τ=BINA=0.2×100×2×8×10×10-4=0.32 N-mAs the current goes counter clockwise and the lines of force goes from N to S so the AD side comes out of the plane of the paper.
