Answer the following question.
Draw the pattern of magnetic field lines of
(i) a current-carrying solenoid and
(ii) a bar magnet.
List two distinguishing features between the two fields.
Two distinguishing features between the two fields:
- The magnetic field of the solenoid can be varied as per our requirements just by changing the current or core of the solenoid whereas the magnetic field of the bar magnet is fixed.
- The magnetic field outside the solenoid is negligible as compared to the bar magnet.
