Directions: In the following questions, a statement of assertion (A) ...
In the case of metallic rod, the charge carries flow through the whole of the cross-section. Therefore, the magnetic field exists both inside as well as outside. However, the magnetic field inside the rod will not decrease as we go towards the axis.

Directions: In the following questions, a statement of assertion (A) ...
Assertion: A direction current flows through a metallic rod, producing a magnetic field only outside the rod.
Reason: There is no flow of charge carriers inside the rod.
Explanation:
To understand the assertion and reason given in the question, let's break down the concepts involved:
1. Direction of current flow: When an electric current flows through a metallic rod, it is the movement of electrons (charge carriers) that constitutes the current. The direction of the current flow in a metallic conductor is conventionally considered to be from the positive terminal to the negative terminal of a battery. This is known as conventional current flow.
2. Magnetic field produced by current: According to the right-hand rule, the magnetic field produced by a current-carrying conductor forms concentric circles around the conductor. The direction of the magnetic field lines can be determined using the right-hand rule, where the thumb points in the direction of the current and the curled fingers give the direction of the magnetic field lines.
Now let's analyze the given assertion and reason:
The assertion states that a direction current flows through a metallic rod, producing a magnetic field only outside the rod. This is true because the magnetic field lines are indeed formed outside the metallic rod due to the current flow.
The reason given for the assertion is that there is no flow of charge carriers inside the rod. This is also true because in a metallic conductor, the charge carriers (electrons) move freely within the conductor due to the applied electric field. However, the movement of charge carriers inside the rod does not contribute to the formation of the magnetic field outside the rod. The magnetic field is a result of the circular motion of electrons around the conductor.
Therefore, both the assertion and reason are true. However, the reason is not the correct explanation of the assertion. The reason explains the absence of charge carrier flow inside the rod, but it does not directly explain why the magnetic field is produced only outside the rod.
Hence, the correct answer is option B: Both assertion (A) and reason (R) are true, but reason (R) is not the correct explanation of assertion (A).
Reason: There is no flow of charge carriers inside the rod.
