WebSo B → ( r) L = 0, so B → ( r) = 0. For an infinite solenoid, Ampère's theorem makes it possible to show very simply that the magnetic is uniform outside. If the magnetic field is zero to infinity, it is zero everywhere outside. One can attempt a dimensional analysis to show that the field is zero at infinity. Web5 nov. 2024 · The magnitude of the magnetic force F on a charge q moving at a speed v in a magnetic field of strength B is given by: (21.3.1) F = q v B sin ( θ) where θ is the angle between the directions of v and B. This formula is used to define the magnetic strength B in terms of the force on a charged particle moving in a magnetic field.
