According to Faraday's Law of Electromagnetic Induction, the induced emf in a loop of wire is directly proportional to the rate of change of the magnetic field applied to the loop. If the rate of change of the magnetic field is doubled, the induced emf would also be doubled assuming all other parameters remain constant.
