  • question_answer
    A frog can be levitated in magnetic field produced by a current in a vertical solenoid placed below the frog. This is possible because the body of the frog behaves as:

    A)  paramagnetic  

    B)  diamagnetic

    C)  ferromagnetic 

    D)  anti-ferromagnetic

    Correct Answer: B

    Solution :

                     When diamagnetic substances are placed in a magnetic field, then they are feebly repelled  in the field. Frog is leviated in magnetic field produced by the current in vertical solenoid below the frog due to repulsion, so body of frog behaves as  diamagnetic substance.
