electromagnetism - Does the direction of magnetic field in a solenoid point from north to south anywhere?



Is there any case where the direction of magnetic field inside a solenoid points from its North Pole to its south?



Answer



No. It is because field lines travel in closed loops i.e loops don't start or stop at any point, or even cross paths.


This is why field lines are from south to north inside the the solenoid not from north to south.
