For the current-carrying solenoid as shown below, draw magnetic field lines and giving reason


#1

For the current-carrying solenoid as shown below, draw magnetic field lines and giving reason explain that out of the three points A, B and C at which point the field strength is maximum and at which point it is minimum.


#2

The magnetic field strength is maximum at point A and is minimum at point C because magnetic field is strong where magnetic field lines are crowded and is weak where magnetic field lines are far apart.
