PhysicsNEET 2022Biot–Savart and Ampère's laws

Moving Charges and Magnetism

Given below are two statements:

Statement I: Biot–Savart's law gives us the expression for the magnetic field strength of an infinitesimal current element () of a current-carrying conductor only.

Statement II: Biot–Savart's law is analogous to Coulomb's inverse square law of charge , with the former being related to the field produced by a scalar source, , while the latter being produced by a vector source, .

In the light of the above statements, choose the most appropriate answer from the options given below:

  1. A.Statement I is incorrect and Statement II is correct
  2. B.Both Statement I and Statement II are correct
  3. C.Both Statement I and Statement II are incorrect
  4. D.Statement I is correct and Statement II is incorrect✓

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
