STANDARD Physics Magnetic Field Due to Current MCQ Question
Two very long, straight, and insulated wires are kept at 90° angle from each other in xy-plane as shown in the figure. These wires carry currents of equal magnitude I, whose directions are shown in the figure. The net magnetic field at point P will be
-μ₀I/2πd (x̂ + ŷ)
μ₀I/2πd (x̂ + ŷ)
Zero
+μ₀I/πd (ẑ)
Correct Answer
Detailed Explanation
The magnetic fields due to the two wires at point P are equal in magnitude but opposite in direction, resulting in a net magnetic field of zero.
