Question
Two fixed long conducting wires cross each other perpendicularly so that they do not actually touch but are close to each other as shown in the figure. Equal current i exist in each wire in the directions indicated. In what region(s) will there be some points with zero net magnetic field?
- IV, III
- III, II
- II, IV
- I, IV
The correct answer is: I, IV
In region I and IV the magnetic fields are equal and opposite
Hence (d) is the correct answer.
