Step-by-step explanation:

The deflection occurs because the circuit becomes 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.

Answer:

The deflection of the magnetic needle shows that electric current is flowing through the wires. The circuit is complete since the free ends of the tester are dipped into a solution. Also, the solution is a good conductor of electricity. So, the magnetic needle shows deflection.
