Homework Help: Magnetic field inside square conductor

  1. Nov 18, 2007 #1
    Hello everybody,

    I got a small question and was wondering if somebody could help me with that.


    I have a square conductor with side length m. I am now trying to figure out what the magnetic field B is at any point inside that square.

    Here is what I've come up with so far and I think I am pretty close:

    The magnetic field at the center is B=(4*u_0*I)/4pi*a)*(cos(pi/4)-cos(3pi/4))

    where a=m/2 and u_0= the permeability of free space

    But how could I change this now to give me the B field for any point x,y inside that loop?

    Is this too advanced for this section? Do I maybe have to post this in the Physics with calculus section?
