But first draw a diagram will ya?

anonymous · Answer

Use LEFT hand rule as these are electrons not positive charges!

agent0smith · Answer

You can still use the right hand rule, and be aware that you just reverse the direction for which you'd point for a positive charge.

anonymous · Answer

Yes you could , or you can use the convention that left hand is used for negative charges and right hand for positive charges and then you don't have to switch directions....to me less chance to make a mistake but to each their own I guess...

agent0smith · Answer

lol it's the same thing. You either use a different hand, or you reverse the direction. 

Chance of making a mistake is the same - you could use the wrong hand in your case, forgetting it's a negative charge, or you could forget to reverse the direction in my case.
