WebWe can now find the net force on the loop: ∑ F → net = F → 1 + F → 2 + F → 3 + F → 4 = 0. 11.17. Although this result ( Σ F = 0) has been obtained for a rectangular loop, it is far more general and holds for current-carrying loops of arbitrary shapes; that is, there is no net force on a current loop in a uniform magnetic field. WebExternal electric field means the electric field that is not generated by the dipole. The rotating force acting on the dipole is the dipole’s torque. This may be performed by … Webfeels a torque when placed in an external magnetic field: τ=×μ Bext The direction of the torque is to line up the dipole moment with the magnetic field: Potential Energy Since the magnetic dipole wants to line up with the magnetic field, it must have higher potential energy when it is aligned opposite to the magnetic field direction and lower theta uvc register
