Question

(hrw8c29p68) Each of two long straight parallel wires 8 cm apart carries a current of 125 A. The figure shows a cross section, with the wires running perpendicular to the page and point P lying on the perpendicular bisector of the line between the wires. Find the magnitude and direction of the magnetic field at P when the current in the left-hand wire is out of the page and the current in the right-hand wire is also out of the page.

Answer 1

The value of By is = (- 6.25×10^-4)

If direction of current is into the page in right hand wire then the magnitude of B will be same but the direction will be in -x direction.

resultant a B 52 } in (-x) direction = 625 P1014 T
