Homework Equations
The Attempt at a Solution
I've attempted to draw the magnetic fields resulting at the location of wire 4 due to wires 1, 2, 3.
I denoted them as B4,1, as in the "The magnetic field at 4 as a result of 1".
Are these correct?
I've been having a really tough time finding the resulting magnetic force for this problem, I want to make sure I've got the first few steps right.
I know that the net magnetic field at 4 will be perpendicular to the current in wire 4 regardless.
So to find the force all I need to do is apply,
[tex]F_{B} = iB[/tex] (We are calculating per meter of wire length)
Is this correct?
How do I get the force in its components if I want?
Thanks again!
