How do you know if there is magnetic torque
WebA magnetic field exerts a torque which tries to align the normal vector of a loop of current with the magnetic field. torque = (# turns) * (current) * (loop area) * (mag field) * sin … 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 …
How do you know if there is magnetic torque
Did you know?
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? Web2. The torque on the dipole is ~˝= ~ B~, where B~is the external magnetic eld. The magnitude of this torque is Bsin , where is the angle between B~and ~(that’s just de nition …
