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.)

"Electricity" Misconceptions Spread By K-6 Textbooks

Is this confusing? Here''s another way to see it. During an electric current, the wires become surrounded with magnetic field. This field IS the electrical energy. Also, whenever a pair of wires is connected to a battery or generator, the two wires become oppositely charged, and they become surrounded with an invisible electrostatic field.
