When an electric current is passed through any wire, a magnetic field is produced around it. Then why an electric iron connecting cable does not attract nearby iron objects when electric current is switched on through it?


When an electric current is passed through a wire, a magnetic field is produced around it, but the strength of such magnetic fields are very weak and is not enough to attract nearby objects. 
Furthermore, the metallic wires of cables are shielded with a cover that prevents the magnetic field to show its effect outside the cable.
