I am reading chapter 8th of Griffiths' electrodynamics (4th edition) on page 361 I stumbled upon this:
For figure 8.3 I don't understand why does the magnetic force of charge q1 points upward? According to right hand rule the thumb should point in the direction of v1 and then fingers curling around, show the direction of B1. This part I think is reflected on the figure because B1 points in the direction of negatve z axis. But then Fm should point in the direction of the palm which is into negative y axis while on the figure it is positive y axis, why?
PS: for Fm coming from q2 all is aligned with my right-hand rule description.
Thanks
