Two very thin metallic wires placed along X- and Y-axes carry equal currents as shown in Fig. AB and CD are lines at `45^@` with the axes. The magnetic field will be zero on the line

A

AB

B

CD

C

segment OB only of line AB

D

segment OC only of line CD.

Text Solution

Verified by Experts

The correct Answer is:
A
(a) All points on AB are equidistant from the two wires. So,
magnetic field are equal and opposite. Thus, they cancel out.
