JEE Main20244 Apr 2024Morning ShiftPhysicsMagnetic Effects of CurrentActual
The magnetic field existing in a region is given by B =0.2(1+2 x) k ~T . A square loop of edge 50 ~cm carrying 0.5 A current is placed in x-y plane with its edges parallel to the x-y axes, as shown in figure. The magnitude of the net magnetic force experienced by the loop is_____ mN .
Correct answer
0
Step-by-step solution
Force on segment parallel to x -axis will cancel each other. Hence F _ net will be due to portion parallel to y -axis. aligned & F=0.5 0.5 6 0.2-0.5 0.5 0.2 5 & =0.5 0.5 0.2 & =0.25 0.2 & =50 10⁻³ ~N & =50 mN aligned
