Question

when the free is of a tester are dipped into a solution the magnetic needle show deflection can explain the reason ​

Answer 1

Answer:

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

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.

Answer 2

Answer:

The deflection of a magnetic needle if a tester is dipped in a solution can be explained. The magnetic field is generated by the current flowing through a tester. The free end of a tester, dipped inside the solution, is a good conductor of electricity. The immersion of tester in the solution makes the circuit complete. When an electric current is carried through tester, it generates a magnetic field because of which needle of the compass deflects.
