The phenomenon of perfect diamagnetism in superconductors is called the . . . . . . .

If a diamagnetic substance is brought near the north or south pole of a bar magnet,it is:

The following graph shows the response of magnetization $M$ of a paramagnetic material to the applied magnetic field strength $H$ for three different temperatures $T_1$,$T_2$,and $T_3$. Which of the following is correct?

$A$ small rod of bismuth is suspended freely between the poles of a strong electromagnet. It is found to arrange itself at right angles to the magnetic field. This observation establishes that bismuth is

The given figure represents a material which is

The materials suitable for making electromagnets should have
