A frog can be levitated in a 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) Antiferromagnetic
To levitate a body, a force must be applied on it which at least balances the body's weight. Since weight will always pull the frog down, the magnetic force on the frog due to the vertical solenoid placed belowit must act in the upward direction. Thus, the frog is repelled by the magnetic field
