Question
Two long, parallel wires are separated by a distance 2 d, as shown below. Wire #1 carries a steady current I out of the plane of the page while wire #2 carries a steady current I out of the page.
At what points in the plane of the page (besides points at infinity), is the magnetic field due to the currents zero?
1. At all points on a circle of radius d centered at either wire.
2. At only point P.
3. At all points on the line SS', a perpendicular bisector of a line connecting the two wires.
4. At all points on the line connecting the two wires.
Two long, parallel wires are separated by a distance 2 d, as shown below. Wire #1 carries a steady current I out of the plane of the page while wire #2 carries a steady current I out of the page.Explanation / Answer
optoin 2 is correct answer
