- (i)(I) In the given circuit diagram, a battery , a key , a resistance and a thick copper wire XY are connected in series and a compass is placed near the wire. What is the purpose of this arrangement ? (II) What conclusion do you draw from it ?
- (ii)Give reasons : (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, aligns along a particular direction. (III) The burnt-out fuse should be replaced by another fuse of identical rating.
