Physics-Biot-Savart Law
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.
