A) \[{{\mu }_{0}}nI\]
B) \[{{\mu }_{0}}\frac{nI}{{{l}^{2}}}\]
C) along the axis of solenoid
D) perpendicular to the axis of coil
Correct Answer: C
Solution :
A solenoid of length l and having n turns carries a current I in anticlockwise direction. The magnetic field is \[\frac{{{\mu }_{0}}nI}{l}\]. Its direction will be along the axis of solenoid.
