    The expression for magnetic induction inside a solenoid of length L carrying a current I and having N number of turns is                                                                                            [MP PMT/PET 1998]

    A)    \[\frac{{{\mu }_{0}}}{4\pi }\frac{N}{LI}\]              

    B)    \[{{\mu }_{0}}NI\]

    C)    \[\frac{{{\mu }_{0}}}{4\pi }NLI\]                              

    D)   \[{{\mu }_{0}}\frac{N}{L}I\]

    Correct Answer: D

    Solution :

       \[B={{\mu }_{0}}ni={{\mu }_{0}}\frac{N}{L}i\]
