Question

when the free ends of a tester are dipped into a solution the magnetic needle shows deflection .can you explain the reason with diagram ​

Answer 1

$\huge \fbox{\underline \blue{Answer-}}$

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.

Hope it helps✌

Answer 2

Answer:

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.
