[SOLVED] predicting path/direction of a charge in a magnetic field (drawings included
Is there any convention to go by when trying to predict the path of a charge in a uniform magnetic field?
I know that a charge makes a circular path upon entering a magnetic field, but that's all. I am not sure how to get the charge's actual direction within a B field: clockwise, counterclockwise, into the page, out of the page...etc.? (I am currently using RHR in which my palm = force, fingers = B field, thumb = velocity.)
example 1: if i am told to steer a PROTON through chambers I, II, III, IV which differ in magnetic field (see link with picture below), can the charge's initial path differ from the resulting velocity vector? yes, right?? In that question, I am given the path (red) of the charge and I am told to draw in the magnetic field, the force vector, and velocity vector in each of the four quadrants. did i do this correctly and why? please see my drawing and help. please. like in chamber I, if i did my drawing correctly then why is the path clockwise, and then in chamber II counterclockwise?
example 2: i am told to steer an ELECTRON through chambers I, II, III, IV, and again label B field, F and v. is my drawing correct? again, in chamber I, why is the path clockwise, and in II counterclockwise? I find that labeling F abd v for chamber III to be especially difficult. :(
thank you for all your help. this is my 1st post. you guys are awesome.

key: red = path of charge, aqua = direction of force, orange = velocity
