A set up consisting of a bulb, salt solution and a magnetic compass is arranged in such a manner that bulb and salt solution come in between the electric wires connected to the cell and hence complete the circuit. The magnetic compass is wrapped with the connecting wires. When switched on, current flows through the salt solution, the bulb glows and the needle deflects. Which of the following effects of current is responsible for this?
