A closed curve encircles several conductors. The line integral `ointvecB.vec(dl)` around this curve is `3.83xx10^-4 Tm.`
(a) What is the net current in the conductor?
(b) If you were to integrated around the curve in the opposite direction, what would be the value of the line integral? Expalin.

Text Solution

Verified by Experts

(a) `oint vecB.vecdl=nu_0I_(encl)=3.83xx10^-4Tm`
`I_(encl)=305A`
(b) `-3.83xx10^-4` since `dvecl` points opposits to `vecB` everywhere.
