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 \(I(dl)\) 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, \(q.\)


1. Statement I is false but Statement II is true.
2. Both Statement I and Statement II are true.
3. Both Statement I and Statement II are false.
4. Statement I is true but Statement II is false.

Given below are two statements: 

Statement I: The magnetic field due to a segment \(\overrightarrow{dl}\) of a current-carrying wire carrying a current, \(I\) is given by:
  \(\overrightarrow{dB}=\frac{\mu_0}{4\pi}~I\left(\overrightarrow{dl}\times\frac{\overrightarrow r}{r^3}\right )\),
where \(\vec{r}\) is the position vector of the field point with respect to the wire segment.
Statement II: The magnetic field of a current-carrying wire is never parallel to the wire.
 
1. Statement I and Statement II are true and Statement I is the correct explanation of Statement II.
2. Statement I and Statement II are true and Statement I is not the correct explanation of Statement II.
3. Statement I is true, Statement II is false.
4. Statement I is false, Statement II is true.
