Introduction to Magnetism, Force on Dielectric in Charged Capacitor Class 12 Physics | JEE Main 2023

In an experiment, a current-carrying rectangular loop of wire is suspended in a uniform magnetic field. It is held in place by a pair of torsion balances. Torsion balances are lengths of material that allow twisting due to a net torque exerted on an object but deliver a counter torque proportional to the angle of twist. The amount of current that travels through the loop remains constant. The uniform magnetic field is varied, and the angle of twist θ is measured. Which of the following observati
