NEET Physics Biot-Savart Law Assertion Reason Question
Assertion (A): The magnetic field produced by a current element is perpendicular to the plane containing the element and the point where the field is measured.
Reason (R): The Biot-Savart Law uses the cross-product of the current element and the position vector to determine the direction of the magnetic field.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false, but R is true.
Correct Answer
Detailed Explanation
The Biot-Savart Law involves a cross-product, which inherently results in a vector perpendicular to the plane containing the two original vectors (the current element and the position vector).
