Why does a moving charge creates magnetic field?
Answer with own, if you answer by internet then you are reported and ur id is deleted..​

Answer 1

Answer:

When ɑn ɑtom spins or orbits it produces ɑ mɑgnetic field ɑs does electricɑl current flowing through ɑ wire. The direction of the spin ɑnd orbit determine the direction of the mɑgnetic field.

When ɑn electricɑl chɑrge is in motion, it creɑtes ɑ mɑgnetic field.

hope this helps you.

Answer 2

Explanation:

As Ampere suggested, a magnetic field is produced whenever an electrical charge is in motion. The spinning and orbiting of the nucleus of an atom produces a magnetic field as does electrical current flowing through a wire. The direction of the spin and orbit determine the direction of the magnetic field.
