A) \[\frac{{{\mu }_{0}}l}{2R}\,\,\text{interior}\]
B) \[\frac{{{\mu }_{0}}l}{2R}\,\,\text{exterior}\]
C) \[\frac{{{\mu }_{0}}l}{2R}\left( 1-\frac{l}{\pi } \right)\,\,\text{interior}\]
D) \[\frac{{{\mu }_{0}}l}{2R}\left( 1+\frac{l}{\pi } \right)\,\,\text{exterior}\]
Correct Answer: A
Solution :
Magnetic field at the centre O \[B=\frac{{{\mu }_{0}}l}{2R}\] and from Right hand thumb rule, the direction of the field is going interior.You need to login to perform this action.
