Questions
Two long parallel wires P and Q are both perpendicular to the plane of the paper with distance 5 m between them. If P and Q carry current of 2.5 A and 5 A, respectively, in the same direction, then the magnetic field at a point half way between the wires is
detailed solution
Correct option is D
In the following figure, magnetic field at mid point M is given byBnet = BQ−BP=μ04π . 2r iQ −iP= μ04π × 22.5 5−2.5 = μ02πTalk to our academic expert!
