Difine magnetic susceptibility of a material. Name two elements, one having positive susceptibility and the other having negative susceptibility. What does nagative susceptibility signify?

For definition, see point number 23 under the heading “Chapter At Glance”. Copper (a diamagnetic material) has negative susceptibility but aluminium (a paramagnetic material) has positive susceptibility. Nagative susceptibility signifies that the material is repelled in a magnetic field and ...

State two characterstic properties distinguishing the behaviour of paramagnetic and diamagnetic materials.

(i) Diamagnetic substances, when placed in a non-uniform magnetic field, tend to move from stronger region of the field to the weaker region. On the other hand, paramagnetic substances move from weaker region of the field to the stronger region.
