Question
For the current carrying solenoid as shown, draw magnetic field lines and give reason to 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?
Solution
- Magnetic field strength outside of the solenoid is minimal. The magnetic field strength at the ends of the solenoid is half that inside. Field strength is thus:
Minimum - at point B; Maximum - at point A.
