Question

why electric current produces magnetic effect in a conductor​

Answer 1

Explanation:

Because an electric current generally consists of moving electrons, a current in a wire produces a magnetic field. In fact, the wire acts as a magnet. Increasing the amount of current in the wire increases the strength of the magnetic field.

Answer 2

Explanation:

you were told that a loop of current-carrying wire produces a magnetic field along the axis of the wire. ... Just as for electric charges, opposite magnetic poles repel and like poles attract. Thus the magnetic field pointing from north to south points in the direction of the force on a NORTH POLE of a magnet.
