WebWhen the magnetic field is on, the torque on the magnet due to the field will tend to align the magnetic moment with the field. If the ball is released from rest with its axis not aligned 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

WebThe torque about this axis is: τ = F (a/2) + F (a/2) = Fa = IabB. ab is the area of the loop, so the torque is, in this case, τ = IAB. This is actually the maximum possible torque, when the field is in the plane of the loop. When the field is perpendicular to the loop the torque is zero. In general, the torque is given by: τ = IA × B WebThe formula used is, τ = m × B = m B sinθ. Where m- magnetic moment and B- magnetic field are applied. When a current loop is said to be placed in a magnetic field, it is believed …
