- How does the magnitude of the induced voltage depend on the time rate of change of the magnetic flux? If one wanted to increase or reduce the induced voltage what could one do?Don't use chat gpt Chatgpt means downvoteA wire loop is spinning on its axis in a uniform magnetic field. Is there an emf induced in the loop? Yes, as long as the angular velocity is nonzero Yes, but only if the angular velocity of the loop is increasing or decreasing Yes, but only if the angular velocity of the loop is constant O No
