NEET Physics Biot-Savart Law Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Current element I dl | (i) Produces a magnetic field dB |
| (b) Magnetic field B | (ii) Vector quantity with dimensions [M T –2 A –1] |
| (c) Permeability of free space μ0 | (iii) Scalar quantity in T m A –1 |
| (d) Direction of dB | (iv) Given by the Right Hand Screw rule |
a-i, b-ii, c-iii, d-iv
a-ii, b-i, c-iv, d-iii
a-iv, b-iii, c-i, d-ii
a-iii, b-iv, c-ii, d-i
Correct Answer
Detailed Explanation
In the context of the Biot-Savart Law, the current element I dl produces a magnetic field dB, the magnetic field B is indeed a vector quantity with dimensions [M T –2 A –1], and the permeability of free space μ0 is a scalar quantity in T m A –1. The direction of dB is determined by the Right Hand Screw rule as stated in the NCERT context.
