What is a solenoid? 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.
A solenoid is a coil of several circular turns of insulated conducting wire, wrapped closely in the shape of a cylinder. Pattern of magnetic field lines of 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.
