Question

.)The electrons are always present and moving inside a conductor. Why there is no magnetic

field near a conductor when no current flows through it?​

Answer 1

Explanation:

Because in the absence of electric field all the electrons are randomly oriented . The net result is that there is no regular movement of electrons in a particular direction to give rise to a current . ... Thus , there is no current .

Answer 2

Explanation:

The magnetic field produced by an electric current is always oriented perpendicular to the direction of the current flow. ... Note that if there is no current there will be no magnetic field. The direction of the current in the conductor (wire) is shown by the central arrow.
