Homework Statement
An infinite wire of parabolic shape carries a current I, find the magnetic flux density B, at the focus
Homework Equations
B=(μ0*I)\(2∏r) I know this is for a straight wire, I'm not sure what i would use for a U shaped wire
The Attempt at a Solution
Well I figure the current is running for one end to the other and the B field around the wire but I don't know what at the focus means, and I'm not sure what the bent U shape/parabolic effects the B field
