Chapter 22, Problem 71GP

CE A proton follows the path shown in Figure 22-56 as it moves through three regions with different uniform magnetic fields, B₁, B₂, and B₃. In each region the proton completes a half-circle, and the magnetic field is perpendicular to the page. (a) Rank the three fields in order of increasing magnitude. Indicate ties where appropriate. (b) Give the direction (into or out of the page) for each of the fields.
