Detailed Solution

The direction of magnetic lines produced by passing a direct current in a conductor is surrounding the conductor and circular nature
The question is based on right-hand palm rule. According to the rule. The lines of the magnetic field will be perpendicular to the flow of current on one side. Magnetic lines never intersect with each other. The magnetic lines will be circular in nature. The direction of the current will be perpendicular where the conductor having magnetic field around. The magnetic lines of force that are produced around the conductor are perpendicular to the direction of the current. A magnetic field of current carrying conductor forms concentric circle around the circle.
