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 containing the current element and the point of observation.
The magnetic field produced by a current element is dependent on the square of the distance from the current element to the point of observation.
The Biot-Savart Law applies only to varying currents, not to steady currents.
The direction of the magnetic field produced by a current element can be determined using the Right Hand Screw rule.
Correct Answer
Detailed Explanation
According to the Biot-Savart Law, the magnetic field produced by a current element is indeed perpendicular to the plane formed by the current element and the position vector to the point of observation, as indicated by the expression involving the cross product. The Right Hand Screw rule also helps determine the direction of the magnetic field.
