Question

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

Answer 1

Answer:

• The deflection in magnetic needle shows that the circuit is complete and the solution conducts electricity, i.e., it is a good conductor.

Answer 2

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.
