Formula for torque in magnetic field
WebThe torque tries to align the normal to the area of the loop with the magnetic field. For a current loop we have defined the magnetic moment μ as. μ = IA n. (magnetic moment = current times area) The torque on a current loop can then be written as τ = μ × B . The magnitude of the torque is τ = μB sinθ. The torque tries to align μ and B. WebThe equation is given by F = q v × B or F = qvB sin θ, where q is the charge, B is the magnetic field, v is the velocity, and θ is the angle between the directions of the magnetic field and the velocity; ... The current will experience no force if it is parallel to the magnetic field. Torque on a current loop.

Webdiscussion of a basic torque formula. The formula for the net torque on any current distribution, which is exact in a constant magnetic field, is given in terms of the “magnetic dipole moment” or simply “magnetic moment” µ→ with: with µ→ itself to be discussed shortly. This cross-product can be taken with respect to any 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 of cross-product). 3. The direction of magnetic torque is given by the RHR for cross-product, or you can just remember that the dipole always wants to line up with

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. τ= IA× B where the area vector is perpendicular to the plane of the loop.
