Question

when the free ends of a teaster are dipped into a solution, the magnetic needle shows deflection,.can you're explain the reason??​

Answer 1

Answer:

It depends on what type of solution you introduce it but it is assumed that if

Answer 2

Answer:

The deflection in the compass needle shows that current is flowing through the wounded wire and hence, through the circuit. The circuit is 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.The deflection in the compass needle shows that current is flowing through the wounded wire and hence, through the circuit.
