Two thin long wires carry currents `I_1 and I_2` along x- and y-axes, respectively, as shown in Fig. Consider the points only in x-y plane.

A

Magnetic field is zero at last at one point in each quadrant

B

Magnetic field can be zero somewhere in the first quadrant

C

Magnetic field can be zero somewhere in the second quadrant

D

Magnetic field in non-zero in second quadrant

Text Solution

Verified by Experts

The correct Answer is:
B, D
(b,d) : In first and third quadrant, direction of magnetic field is
opposite due to the two wires. So, magnetic field can be zero
only in first and third quandrants not in second and fourth.
Hence, (b) and (d) are correct.
