WebBy the FLB=×i ext force law, we know that a current loop (and thus a magnetic dipole) feels 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 WebThe torque exerted then produces a change in angular momentum which is perpendicular to that angular momentum, causing the magnetic moment to precess around the direction of the magnetic field rather than settle down in the direction of the magnetic field. This is called Larmor precession.

WebJul 29, 2024 · Solar radiation pressure torque Radiation (electromagnetic waves) carries momentum according to Maxwell’s theory of electromagnetism. Upon hitting a surface, this momentum can be transferred to the surface. The amount of momentum transferred depends on the type of surface being illuminated. WebSo the torque will be = mB x 2lsinθ = 2lm x B x sinθ (M= 2lm= magnetic dipole moment) Since M and B, both, are vectors the torque acting on a magnet suspended in the magnetic field can be expressed as the cross-product of M and B as follows. = M B Units of M Units of M can be obtained from the relation: = MB sin θ So, M = /B sin θ roofing contractors frisco tx
