Question
A positively charged particle is momentarily at rest in a uniform magnetic field. Is there a magnetic force acting on this particle? Explain.
Step 1
This force is given by the expression: \[ F = q \cdot (v \times B) \] where \( q \) is the charge carried by the particle, \( v \) is its velocity, and \( B \) is the magnetic field. Show more…

Does the magnetic force ever do work on a moving charged particle?
A uniform magnetic field is directed horizontally toward the north, and a positive charge is moving west through this field. Is there a magnetic force on this charge, and if so, in what direction? Explain.
