A thin infinitely large sheet lying in yz plane carries a current of linear current density `lambda`. The current is in negative y direction and `lambda` represents current per unit length measured along z-axis. Find the magnetic field near the sheet : (Magnetic field due to the sheet will be parallel to sheet)
(Long sheet with `lambda = ("current")/("length")`)
A. `B = (mu_(0)lambda)/(2)`
B. `B = mu_(0)2lambda`
C. `B = mu_(0)lambda`
D. `B = (mu_(0)lambda)/(4)`
