Magnetic field due to currentHard
Question
A frog can be levitated in a magnetic field produced by a current in a magnetic field produced by a current in a vertical solenoid placed below the frog behaves as :
Options
A.paramagnetic
B.dimagnetic
C.ferromagnetic
D.antiferromagnetic
Solution
The frog is levitate in the magnetic field due to repulsion. It suggests that the body of frog is acting as ferromagnetic material.
