Question

Draw the pattern of magnetic field lines of a solenoid through which a steady current flows. What does the pattern of field lines inside the solenoid indicate?

Answer 1

The pattern of magnetic field lines of a solenoid through which a steady current flows:

The pattern of magnetic field lines inside a current-carrying solenoid indicates that the magnetic field is uniform, i.e., strength of the magnetic field is the same, everywhere inside the solenoid.
