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 change 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 statement choose the most appropriate answer from the options given below:
- A
Both statement I and Statement II are incorrect
- B
Statement I is correct and Statement II is incorrect
- C
Statement I is incorrect and Statement II is correct
- D
Both statement I and Statement II are correct
Biot-Savart's law: .
It correctly expresses the contribution to the magnetic field from an infinitesimal current element of a current carrying conductor, so Statement I is correct.
The source is a vector quantity (not a scalar), while the electric charge in Coulomb's law is a scalar. Statement II reverses these, so it is incorrect.
