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

A.VERIFIED ANSWERfact-checked by tutors

Soln:

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