Question

When the free ends of tester are dipped into a solution, the magnetic needle shows

deflection. (2)​

Answer 1

Answer:

here

Explanation:

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.

Answer 2

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.
