Question

A frog can be deviated in a magnetic field produced of 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

Answer 1

Answer: (B)

Diamagnetic

Solution: Few of the substances, when kept in a magnetic field get magnetized feebly in the direction opposite to the direction of the magnetic field and when they come in the influence of the strong magnet they get repelled from them. The body of the frog behaves like a diamagnetic substance, hence the smallest magnetic field placed below the body of the frog will be strong enough to lift it.

Hence, the correct option is (B).
