Question

The magnetic field at the centroid of the triangle is

• A. \( 1.66 \times 10^{-5} \, \text{T} \)
• B. \( 1.22 \times 10^{-5} \, \text{T} \)
• C. \( 1.33 \times 10^{-5} \, \text{T} \)
• D. \( 1.44 \times 10^{-4} \, \text{T} \)

Hint:

For a current-carrying triangle, the magnetic field at the centroid can be calculated using the Biot-Savart law.

Answer 1

The Correct Option is A

The magnetic field at the centroid is determined by applying Ampere’s Law and calculating the field produced by currents in the sides of the triangle.
