Question

When the free ends of a tester are dipped into solution,the magnetic needle show deflection .can you explain the reason?

Answer 1

The compass needle shows a deflection which concludes that current is flowing through the wire. The current becomes complete as the free ends of the tester are immersed inside the solution. So, the solution is conducting solution and that is the reason why a deflection is obtained in the compass needle.

I hope it is helpful to u...

Answer 2

Answer:

Yes, the solution does conduct electricity. Compass needle shows deflection due to magnetic effect of electric current.
