@Jim I should flag that comment for being funny :P On topic though: take a look at the Lorentz force wikipedia page and keep in mind that the charge $q = -e$ of an electron is negative. Edit: I see that I completely missed the fact that there was already a good answer to your question. You might want to accept that answer if it cleared up your confusion. ;) – Wouter Jun 19 '13 at 20:54
