Answer:
Mark me as BRAINLIEST
Explanation:
Electric current produces magnetic effect. When free ends of a tester are dipped in the solution, the solution conducts electricity as it is a good conductor of electricity. So, the circuit is now complete. Hence, electricity passes through the wire causing deflection of the magnetic needle of a compass.

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.
