Question

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

Answer 1

Explanation:

When the free ends of a tester are dipped into a solution ,the magnetic needle shows deflection this is because electric current flowing through a wire produce electric current . Explanation: When the free ends of a tester are dipped into a solution then the circuit gets complete.

Answer 2

Answer:

$\huge\rm\orange{Answer:}$

The compass needle shows a deflection which concludes that current is flowing through the wire. The circuit becomes complete as the free ends of the tester are immersed inside the solution. So, the solution is conducting solution hence deflection is obtained in the compass needle.
