100 Turn Rectangular Coil Abcd In X Y Plane Is Hung From One Arm Of Balance Shown In Figure

A 100 turn rectangular coil ABCD (in X-Y plane) is hung from one arm of a balance (shown … additional mass m must be added to regain…


Key concept: Here we use the concept of magnetic force on straight current carrying conductor placed in the region of external uniform magnetic field. The magnetic force exerted on CD due to external magnetic field must balance its weight. And spring balance to be in equilibrium net torque should also be equal to zero.
