Question

when the free ends of a conductivity tester made by using a battery connected to a wire wandered around a compass are dipped into a solution the magnetic needle shows deflection can you guys the reason for this deflection ? ​

Answer 1

Answer:

s the needle shows deflectoin

explanation

as the free ends of a tester ar dipped into a solution the liquid betweenthe two ends allow the electric currentto pass and the circuit of the tester becomes complete when the current passes through it,it establish a magnetic effect and hence magnetic needle shows deflection

In order words we can say that solution is a hood comductor of electricity thus the needle shows deflection

Answer 2

Answer:

The deflection in the compass needle shows that current is flowing through the wounded wire and hence, through the circuit. The circuit is complete since free ends of the tester are dipped in a solution. The solution is certainly a conducting solution. This is the reason why the compass needle shows a deflection.
