Ok I think I got it. According to wikipedia, there must be an opposite reactive force to the force produced by lorentz equation[PLAIN]http://upload.wikimedia.org/math/1/1/7/117693a4a6d55502f66788d04f156c72.png. This opposite reactive force pushes the electron away. Am I right?
Homework Statement
A cathode-ray tube aims electrons parallel to a nearby wire that carries current in the same direction. What will happen to the cathode rays in terms of deflection?
The Attempt at a Solution
[/B]The Motor force deflects the cathode rays ?
Homework Statement
Two parallel conductors each carry 10 A of current in the same direction.
a) What is the magnetic field strength at the midpoint between these wires? (answer = 0T)
b) What is the field strength at the same point if the current ran in opposite directions? (answer = 4.0x10^-4T)...
