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 current element and the point of observation.
Reason (R): The direction of the magnetic field due to a current element is given by the right-hand rule applied to the cross product of the current element vector and the position vector.
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 states that the magnetic field dB produced by a current element Idl is perpendicular to the plane formed by Idl and the position vector r, as described by the right-hand rule for cross products.
