When the free ends of a tester are dipped into a solution, the magnetic needle shows deflection. Can you explain the reason?
Solution has ions present in it causing electric current. Electric current produces magnetic effect causing deflection of the magnetic needle of a compass. Therefore, when a tester is dipped in the solution, the needle shows deflection, being a good conductor of electricity.
