1.	If current in one coil becomes steady then magnetic field lines becomes
Answer» Explanation: Magnetic effect. A current flowing in a wire produces a magnetic field AROUND the wire. In a COIL, the field from ADJACENT turns is in the same direction so it adds up. This is why a coil of wire with say 500 turns makes a much stronger magnet than ONE with 5 turns.
