NEET Physics Biot-Savart Law MCQ Question
Which of the following statements about the Biot-Savart Law is correct?
The magnetic field produced by a current element is always perpendicular to the plane formed by the current element and the position vector.
The Biot-Savart Law can only be applied to straight current-carrying wires.
The direction of the magnetic field produced by a current element is determined by the Right Hand Rule, but its magnitude does not depend on the angle between the current direction and the position vector.
The Biot-Savart Law indicates that the magnetic field produced by a closed loop of current must be uniform throughout the space surrounding it.
Correct Answer
Detailed Explanation
The Biot-Savart Law states that the magnetic field produced by a current element is indeed perpendicular to the plane formed by the current element and the position vector, as highlighted in the NCERT context regarding the direction of the field and the use of the Right Hand Rule. Options B, C, and D misinterpret the applications and implications of the law.
