A steady electric current is flowing through a cylindrical conductor.T...
electric field that should be created when a steady current is passing through a part of a circuit, then my answer is that the conducting cylindrical wire will not produce an electric field but only magnetic field as there is flow of just electrons and not protons.The electric field,on the other hand will be zero because the conductor(here) is electrically neutral.

Explanation:
When a steady electric current flows through a cylindrical conductor, several characteristics can be observed in the vicinity of the conductor. Let's analyze each statement to understand why option D is the correct answer.
1. The electric field in the vicinity of the conductor is zero.
- This statement is not true. When a current flows through a conductor, an electric field is established around it. This electric field is responsible for the flow of electrons in the conductor. Therefore, the electric field is present in the vicinity of the conductor.
2. The magnetic field in the vicinity of the conductor is zero.
- This statement is also not true. According to Ampere's law, a steady electric current flowing through a conductor produces a magnetic field around it. This magnetic field follows the right-hand rule, where the fingers of the right hand curl in the direction of the current, and the thumb points in the direction of the magnetic field. Therefore, the magnetic field is present in the vicinity of the conductor.
3. The electric field at the axis of the conductor is zero.
- This statement is true. Due to the cylindrical symmetry of the conductor, the electric field at the axis of the conductor is zero. The electric field lines produced by the flow of current are radially symmetric and perpendicular to the axis. Hence, at the axis, the electric field cancels out in all directions, resulting in a net electric field of zero.
4. The magnetic field at the axis of the conductor is zero.
- This statement is not true. The magnetic field at the axis of the conductor is not zero. It forms concentric circles around the axis, with the magnetic field lines being parallel to the axis.
Conclusion:
Based on the analysis above, we can conclude that option D, which states that the electric field at the axis of the conductor is zero and the magnetic field at the axis of the conductor is zero, is incorrect. The correct answer should be option A, which states that the electric field in the vicinity of the conductor is zero and the magnetic field at the axis of the conductor is zero.
