1. The problem statement, all variables and given/known data There are three horizontal areas side by side - a completely uniform area. Areas 1 and 3, the magnetic fields are going into the page and area 2's field is going out of the page. An electron enters area 2 (the middle region). What is its path? 2. Relevant equations F = qvB sin theta 3. The attempt at a solution I know it's a circular path - what I was wondering was, since in regions 1,2, and 3 the magnetic fields are all perpendicular to the velocity vector of the electron (and therefore theta stays the same), does the circular path change in any way throughout the regions?
