Thanks to experimental observations, Faraday concluded that an electric current can be generated by a variable magnetic field. Which of the following statements is true? The electromotive force that is generated in a circuit depends only on how the magnetic field varies over time An electromotive force is always generated in a circuit by a varying magnetic field The electromotive force observed in a circuit depends on how the flux of the magnetic field varies The deformation of the circuit does not affect the induced electromotive force
