as u know torque is given by NI(A X B) where N and I are number of loop turns and current magnitude respectively, A is area in vector and B is magnetic field in vector. regarding the direction of area : what normal to take as a direction, is at that which makes acute angle with magnetic field (supposing that magnetic field has a specific direction) ? and if the normal to the area is perpendicular to the field so which normal to choose then ? and does the equation of the torque indicate that its direction is independent from the direction of current ?
