Question

Two very long, straight and insulated wires are kept at 90º angle from each other In xy –
plane as shown in the figure.
These wires carry currently of equal magnitude I, whose directions are shown in the figure. The met magnetic field at point P will be:
(A) (μ₀l/2πd)(xˆ+ yˆ) (B) (+μ₀l/πd)(zˆ)
(C) Zero (D) (–μ₀l/2πd)(xˆ+ yˆ)

Answer 1

Answer:

C. is the correct

Explanation:

both the wire have same and opposite magnetic field so that they will cancel each other.

hope the answer will help you
