\nInside a current-carrying long solenoid, the magnetic field is strong and uniform. The magnetic field lines are parallel to the axis of the solenoid and are close to each other, indicating a uniform field. They are essentially parallel straight lines within the solenoid.
\n<\/section>\n
\nThe magnetic field inside an ideal long solenoid is uniform and axial.
\n<\/section>\n
\nOutside the solenoid, the magnetic field is weak and spreads out. The magnetic field lines form closed loops, emerging from one end (North pole) and entering the other end (South pole), similar to a bar magnet, but the field is concentrated and parallel inside.
