$A$ 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

Needles $N_{1}$,$N_{2}$,and $N_{3}$ are made of a ferromagnetic,a paramagnetic,and a diamagnetic substance,respectively. $A$ magnet when brought close to them will

$A$ small bar of diamagnetic substance is placed in a non-uniform magnetic field. In which direction does it move? Explain.

The materials suitable for making electromagnets should have

Given below are two statements:
Statement-$I$: Susceptibilities of paramagnetic and ferromagnetic substances increase with decrease in temperature.
Statement-$II$: Diamagnetism is a result of orbital motions of electrons developing magnetic moments opposite to the applied magnetic field.
Choose the $CORRECT$ answer from the options given below:

If the magnetic dipole moment of an atom of diamagnetic material,paramagnetic material,and ferromagnetic material are denoted by $\mu_d, \mu_p, \mu_f$ respectively,then:
