A wire in which the electric current is changing will create a changing magnetic field: by the principle of magnetic induction, this can also create an electric field. The electric field typically acts in a direction to oppose the change in current (so, opposing the current flow if it''s increasing, supporting the current flow if it''s decreasing.)
