A conductor consists of an infinite number of adjacent wires, each infinitely long & carry a current `i`.Show that the of `B` will be as represented in figure & that `B` for all points in front of the infinite current sheet will be given by, `B=(1//2) mu_(0)ni`, where `n` is the number of conducting wires per unit length.

Answer

B

Explanation

`ointvecB.dl=mu_(0)I`
`Bl+Bl=mu_(0)[n|i] B=(mu_(0)ni)/2`
