Homework Statement
A square loop, with sides of length L, carries current i. Find the magnitude of the magnetic field from the loop at the center of the loop, as a function of i and L. (Use any variable or symbol stated above along with the following as necessary: μ0.)
Homework Equations
magnetic field outside of a conductor:
u_0*I*r/A
The Attempt at a Solution
I got u_0*I*L/L^2
Not really sure what I should be doing differently? If it was in the shape of a circle it'd be easy, but because it's in a square, it's harder.
