When the free ends of a magnetic tester are dipped into a solution, the magnetic needle shows deflection. Can you explain the reason?
Asked by Topperlearning User | 04 Jun, 2014, 01:23: PM
answered-by-expert Expert Answer

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.
