Learning Goal: To understand the terms in Faraday's law and to be able to identify the magnitude and direction of induced emf. Faraday's law states that induced emf is directly proportional to the time rate of change of magnetic flux. Mathematically, it can be written as E=???B?t, where E is the emf induced in a closed loop, and ??B?t is the rate of change of the magnetic flux through a surface bounded by the loop. For uniform magnetic fields the...

Question7 1 pts Which statement is correct regarding Faraday's Law? O An emf is induced around a closed loop if there is a electric flux through the loop changes. The magnitude of the emf is proportional to the rate the electric flux changes with time. An emf is induced around a closed lool if the magnetic flux through the loop changes with position. The magnitude of the emf is proportional to the rate the magnetic flux changes with position O...

Question 1 Select the correct answer(s): When considering electromagnetic induction, Lenz's Law determines the magnitude of the emf induced across the ends of a coil of wire that is rotating in a magnetic field. The smaller the change in magnetic flux, the greater the induced emf. Faraday's Law can be used to calculate the magnitude of an induced emf. Electric current can be induced by a changing magnetic field. Submit Answer Tries 0/3
