NEET Physics Biot-Savart Law MCQ Question

Type: MCQ-fact-Medium-Class 12

What is the expression for the magnetic field due to a current element according to the Biot-Savart Law?

A

B = (μ0/4π) * (I * dl * sinθ) / r^2

B

B = (μ0/4π) * (I * dl) / r

C

B = (μ0/4π) * (I * dl * cosθ) / r

D

B = (μ0/4π) * (I * dl * θ) / r

Correct Answer

Option A

Detailed Explanation

The correct expression derived from the Biot-Savart Law is B = (μ0/4π) * (I * dl * sinθ) / r^2, where dl is the current element and r is the distance from the current element to the point where the magnetic field is being calculated.
