Answer:

Even in a current-carrying loop, the right-hand thumb rule is observed and followed. This demonstrates that magnetic field lines are present all around the conducting wire. However, because of the circular shape of the conductor, field lines located at various points throughout the loop appear to be forming a ring around the perimeter of the loop. This appears to be a small ring that is looping around the outside of a larger ring.

When the number of coils in a system is increased, the magnetic field becomes stronger. As a result, the strength of the magnetic field increases proportionally to the number of turns in a coil of wire.
