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 (Idl) 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, Idl 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. [NEET 2022]
Text Solution
Verified by ExpertsB
According to Biot-Savart's law, magnetic field due to small current element Idl, at a distance r from it is given as
Thus, current element Idl is a vector quantity. Hence, Statement I is correct and Statement II is incorrect.
