Answer 1

Behaviour of magnetic field lines in (fig) i and ii.

Main distinguishing feature:

Paramagnetic	Diamagnetic
1) It tends to move from weaker to stronger region 2) Field lines passing through it is higher.	1) It tends to move from higher to lower strength region 2) Field lines passing through it is lower.
