Final answer:
The fields that interact with electromagnetic waves generated by an electrically charged wire are the electric field and the magnetic field.
Step-by-step explanation:
An electromagnetic wave is generated by a moving electric charge. When an electric charge oscillates, it produces both an electric field (E) and a magnetic field (B). These two fields are closely related and propagate as an electromagnetic wave. As an electrically charged wire carries current, it generates a magnetic field around it. Together, these changing electric and magnetic fields propagate through space as electromagnetic waves. Therefore, the fields that interact with electromagnetic waves generated by an electrically charged wire are the electric field and the magnetic field.
