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:

because the north end shows the north pole and so forth and shows the South Pole attraction and same ends repel each other and different tents like a North Pole and South Pole will be attracted

➡ 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.
