Electric fields

  1. Sep 2, 2009 #1
    When a DC flows through a wire, does the electric field vary?
    If a changing electric flux produces a magnetic field, then electric field will have to vary constantly, right?
    If that's not the case, then what produces a magnetic field around a conductor carrying current?

    Yes, that is correct.

    The motion of the electrons is what causes the magnetic field to appear.
