WebApr 8, 2024 · Torque experienced by a Current Loop in a Uniform Magnetic Field. We know that the current loop when placed inside the magnetic field, behaves like a magnetic dipole where it has a North and the South pole. So, magnetic moment, M = IA. Now, consider a rectangular loop placed inside the magnetic field. Explanation for Torque on Current Loop WebA torque is a vector quantity which means that it has both a magnitude (size) and a direction associated with it. If the size and direction of the torques acting on an object are exactly balanced, then there is no net torque acting on the object and the object is said to be in equilibrium. At what condition torque is zero?
