(a) Calculate the magnetic field at the point P midway between the wires in the plane of the page. And (b) Calculate the magnetic field at the point Q 1.0 cm from the right of the wire 2. The point Q is in the plane of the page.
Solution:
THe magnetic field due to current carrying long wire B =
In the midway between two wires, the direction of magnetic field will add each other and will be in negative y direction.
So, Beff =
= 2X10^-7X200 = 4X10^-5 Ans
In the second part, both the magnetic fields will oppose each other in direction. THe direction due to right wire will will be in positive y direction while the direction due to left wire will be negative y direction.
So, in this case Effective Magnetic Field Beff =
= 2X10^-7X66 = 1.33X10^-5 Ans
