Week 8 - Magnetic Field and Magnetic Forces
... Particles with nonzero components of velocity at nonparallel with B end up spiralling around the field lines. b) If the magnetic field do no work, how can it have a significant effect on a particles motion? Are there any other examples for which a force has a significant effect on the motion without ...
