Answer 1

$\huge\fcolorbox{black}{lime}(Answer$

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
