How To Find the Torque on a Current Loop in a Magnetic Field

WebMagnetic Torques and Amp's Law. A magnetic field exerts a force on a straight wire carrying current; it exerts a torque on a loop of wire carrying current. Torque causes an object to spin around a fixed axis. Each loop of current has a direction associated with it: its normal vector is perpendicular to the loop, in the direction given by the ... WebAny force that is not parallel to the radial vector will have a component that is perpendicular to the radial vector. This perpendicular force will cause the material to want to rotate in the direction of the perpendicular component. This is called a moment of force or torque. easter brunch des moines 2022

"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 " - How do you know if there is magnetic torque
