NEET Physics PYQ – Moving Charges and Magnetism Practice Set

Q 1 :

Given below are two statements: [2022]

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

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

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

Both Statement I and Statement II are correct.
Both Statement I and Statement II are incorrect.
Statement I is correct and Statement II is incorrect.
Statement I is incorrect and Statement II is correct.

(3)

Statement I is correct, but statement II is incorrect because the magnetic field is produced by vector source $I d l$ and the Coulomb’s force is produced by scalar source $q$ .
