The two effects of electric current are, , aa (i) Heating effect, , Cell Switch, in OFF (ii) Magnetic effect, , position, , 6. When th, ' ne e current is switched ON through a, sho ohn eben ona board. Draw wire, a compass needle kept nearby gets, indica’ a you connect their deflected from its North-South position., s with wires to make a battery of four Soe, Ans. When the current is switched ON through, awire or a coil, there is a magnetic field created, around the coil or wire and we can say that the, wire or coil gets magnetised. Thus, a compass, needle kept nearby gets deflected from its, North-South position due to other magnet, formed by current carrying wire or coll., , a all Fe 7. Will the compass needle show deflection, when, nect all the cells, we should oo the switch in the circuit shown by figure is, inal of one cell to positive terminal closed?, , , , Ans. Yes, the compass needle shows the, , deflection, when switch i, complete. On closing the circuit, current flows, oil and it gets magnetised. Thus,, , due to this magnetic effect of current, compass, , needle shows deflection.
