Two long straight wires piece on the plane of the paper at vertices of an equilateral triangle. They each carry 2 A, out of the paper. The magnetic field at the third vertex has a magnetic of...?
The third vertex is the top of the equilateral triangle. I don't know what equation to use to figure this one out. I know that the magnetic field is eqaul to u0*I/2*pi*r...so do I figure out the magnetic field for each of the straight wires and add together?
(The answer should be 1.7*10^-5 T.)
