... Now let’s see what happens in S’, where the particle is at rest and the wire is moving past to left with the speed v. For simplicity, we set the velocity v0 of the particle is the same as the velocity v of the conduction electrons. Because the particle is now at rest, there is no magnetic force on i ...

... (a) IDENTIFY: Apply Eq.(27.2) to relate the magnetic force F to the directions of v and B. The electron has negative charge so F is opposite to the direction of v B. For motion in an arc of a circle the acceleration is toward the center of the arc so F must be in this direction. a v2 / R. SET UP ...
