Two infinitely long wires carry current as shown in Figure. Find the magnetic field inten sity at the points P, P and P* |
|
Answer» <P> Solution :`At P,B_p = (mu_0I)/(2PI)[1/x + (1)/(r-x)]``At P.B_(p) = (mu_0I)/(2pi)[1/x - (1)/(r+x)]` and at `P..,B_(P^**)=(mu_0I)/(2pi) [1/x-(1)/(r+x)]`(with the same CURRENT )
