User: Which of the following is NOT true of electromagnetic waves? A. An electric field is created in any region of space in which a magnetic field is changing with time. B. A magnetic field is created in any region of space in which an electric field is changing with time. C. Induction of electric fields by changing magnetic fields occurs only if a conducting material is present. D. Induction of magnetic fields by changing magnetic fields occurs even in the absence of a conducting material.







Weegy: the answer is A. [ An electric field is created in any region of space in which a magnetic field is changing with time. For reference An electric field is the region of space surrounding electrically charged particles and time-varying magnetic fields. The electric field depicts the force exerted on other electrically charged objects by the electrically charged particle the field is surrounding. The concept of an electric field was introduced by Michael Faraday. ]
