Give reasons for the following :
(i) There is either a convergence or a divergence of magnetic field lines near the ends of a current carrying straight solenoid.
(ii) The current carrying solenoid when suspended freely rests along a particular direction.
(iii) The burnt out fuse should be replaced by another fuse of identical rating.

(i) There is either a convergence or a divergence of magnetic field lines near the ends of a current-carrying straight solenoid because the strength of the magnetic field is higher near the poles /ends of the solenoid.

(ii) The current carrying solenoid when suspended freely rests along a particular direction because a current carrying solenoid behaves as a bar magnet.

(iii) If a fuse , with a defined rating , is replaced by one with a larger rating then the fuse wire will not burn even when a current greater than safe limit is flowing. As a result the electrical circuit / appliances will be damaged.
