Question : 20
Total: 100
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, Id 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
