ah. thanks for the help.

see attached pic. where A & B are condenser lenses in an EM, so they are fields generated by a coil. A) the field & the velocity are the same direction B) they are opposite (both only shown on one side of the axis). is this correct , with the electron in blue & the positron in red?

in a microscopy class: problem is to illustrate the path of a positron on both sides of the axis in a coil produced magnetic field. consider both cases of the particle's velocity and the magnetic field being a)in the same direction & b)in opposite directions. i have no clue. any help? would it...
