Question

How does Orested found that current carrying conducter produces magnetic field?
​

Answer 1

Answer:

Electricity can be used to produce a magnetic field. Magnetism produced by electricity is called electromagnetism. In 1820, Oersted discovered by accident that electric current creates a magnetic field. ... Oersted also used a compass to find the direction of the magnetic field around a wire carrying current

Answer 2

Answer:

The Magnetic Field Due to a Current in a Straight Wire:

The magnetic field lines are concentric circles as shown in Figure. The spacing between the circles increases as you move away from the wire. This shows that the strength of the magnetic field decreases as the distance from the wire increases.
