प्रश्न
What will happen to a compass needle when the compass is placed below a wire with needle parallel to it and a current is made to flow through the wire? Give a reason to justify your answer.
उत्तर
When the current is reversed, the magnetic needle will display deflection in the other direction. The magnetic effect is present whenever a conductor is conveying a current. OERSTED states that "when an electric current is passed through a conducting wire, a magnetic field is produced around it."
