Homework Statement
Current, I, flows around symmetrical loop of thin wire.
The loop comprises 2 halves (semicircle & triangle). Distance from vertex of triangle equals radius, a, of the semicircle.
Find the mag' field at axis of loop (where axes coss)
Homework Equations
Could I use Gauss' law ∫s E.dS= 1/εo ∫v ρ(r) dv
Amperes law ∫c B . dl
Or is this just as easy to do wit Biot-Savart Law δB(r) = . . . . . . . . .
I have a good feeling that I can use symmetry to simplify this without getting too bogged down in maths.
Which of these are the ones I could use most?
