Question

when the free ends of a tester are dipped into a solution the magnetic needle shows deflection . can u explain the reason .........



plzz help me and give me the answer so that i can give the answer to my sister...​

Answer 1

The magnetic needle shows deflection due to the current passing through the wire wound around it. The current will pass only when the circuit is complete i.e. the when the solution allows electric current to pass through it. So, the magnetic needle deflects to show that the given solution is conducting in nature.

Answer 2

Heya mate!!

When the free ends of a tester are dipped into a solution ,the magnetic needle shows deflection this is because electric current flowing through a wire produce electric current

Hope it helped u dear ✌️✌️
