    Which one of the following are used to express intensity of magnetic field in vacuum?

    A) Oersted              

    B)        Tesla     

    C)        Gauss                   

    D)        None of these

    Correct Answer: A

    Solution :

                    The oersted is the CGS unit of magnetic field strength (or magnetic induction). In SI units, 1 oersted \[=\frac{1000}{4\pi }Am\] \[=79.577\text{ }Am\] While SI unit measuring magnetic flux density is tesia and gauss is the CGS unit of magnetic flux density or magnetic induction.
