Biot-Savart Law

2022 1 question

1. 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 ($I\,d\vec{l}$) of the 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, $I\,d\vec{l}$, 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
