The magnetic field lines inside the solenoid are in the form of parallel straight lines, indicating a uniform magnetic field at all points inside the solenoid.

One end of the solenoid behaves as a magnetic north pole, while the other end behaves as the south pole.

The pattern of magnetic field lines around a solenoid is similar to that around a bar magnet.

A solenoid is a coil of many circular turns of insulated copper wire wrapped closely in the shape of a cylinder.

The convergence of the concentric circles at the center makes the arcs of these circles appear as straight lines, creating a distinct magnetic field pattern.

Applying the right-hand rule reveals that every section of the wire contributes to magnetic field lines in the same direction within the loop, enhancing the overall magnetic effect.

At the center of the circular loop, the arcs of the large concentric circles appear as straight lines, creating a unique magnetic field pattern.

he size of the concentric circles depends on the distance from the wire, following an inverse relationship similar to that observed with a straight wire.

The magnetic field lines around a current-carrying circular loop form concentric circles, and their size increases with distance from the wire, creating a pattern that gradually enlarges.

Directly below, the magnetic field lines circulate counterclockwise, and directly above, they circulate clockwise around the power line.
