प्रश्न
The strength of magnetic field inside a long current carrying straight solenoid is
विकल्प
more at the ends than at the centre
minimum in the middle
same at all points
found to increase from one end to the other
Advertisements
उत्तर
same at all points
Explanation -
Inside the solenoid, magnetic field lines are parallel to each other hence forming a uniform field strength which indicates that the magnetic field is the same at all points inside the solenoid.
