Homework Statement
[PLAIN]http://img695.imageshack.us/img695/5023/directionofforce.jpg
Basically I have to work out the force acting on a current-carrying wire in a magnetic field.
Homework Equations
Fleming's Left Hand Rule
(http://en.wikipedia.org/wiki/Fleming's_left_hand_rule_for_motors)
The Attempt at a Solution
Ok so for the first question (the one on the left)
index finger - pointing up
middle finger - pointing right
my thumb was pointing "out"
so the direction of the force acting on the wire was just "out"
For the second question
index finger - up
middle finger - ?
I'm totally stumped on what direction the current is flowing in :(
