Lecture 4, Oct. 4: Lorentz force (Qs)
- Read foot note 3, to clear up confusion for the number of integration constants.
- When we consider the time-reversal symmetry of this problem, we do not reverse the direction of $\vec{B}$, taking it as given. If we can reverse the direction of $\vec{B}$ as well as the direction of the particle's motion, then the time reversal symmetry would be valid. Read end of page 4, to see why sometimes $\vec{B}$ is not reversible.
