Long Answer Type Questions: c) What is the shape of field lines inside a current-carrying solenoid? What does the pattern of filed lines inside a current-carrying solenoid indicate?
d) List three ways in which the magnetic field strength of a current-carrying solenoid can be increased?

Answer:

c) When the magnetic field lines inside a current-carrying solenoid are parallel to one another and in straight lines, the magnetic field inside the solenoid is uniform.

d) When employing a current-carrying solenoid, the magnetic field intensity can be enhanced by increasing the number of turns in the solenoid, using a soft iron as a core, and increasing the amount of current flowing through the solenoid.
