Name the suitable material for an electromagnet.

What is the Meissner effect? Explain.

Curie temperature is the temperature above which

The most appropriate magnetization $M$ versus magnetising field $H$ curve for a paramagnetic substance is

Suppose a small cylinder of a paramagnetic substance and a small cylinder of a diamagnetic substance are placed between the (parallel) pole pieces of a strong magnet,so that they are aligned along the direction of the field lines. Will they attract or repel each other?

The relative permeability is represented by $\mu_r$ and the susceptibility is denoted by $\chi$ for a magnetic substance. Then for a paramagnetic substance:
