The magnetic field strength is more in the region where the field lines are crowded. This means the field strength is maximum near the poles and it reduces as we go away from the poles. The direction of the magnetic field is also reversed.

    1. In the magnetic field pattern around the solenoid, the field lines are denser near the poles, showing that the magnetic field is stronger at these regions outside the solenoid. The direction of the field is from the north pole to the south pole outside the solenoid. When the electric current in the circuit is reversed, the direction of the magnetic field also reverses, interchanging the north and south poles of the solenoid while maintaining the same magnetic field strength.
