Chapt. 31 Faraday’s Law of Induction and Inductors Multiple-Choice Problems 031 qmult 00100 1 1 2 easy memory: Faraday’s law of induction 1 1. The general form of is E = contintegraldisplay ( vector E + vectorv × vector B ) · dvectors = d Φ dt , where E is the induced emf around a closed contour, vector E is the Maxwell-Faraday law induced electric field, vectorv is the velocity of the contour in the observer’s inertial frame of reference, vector B is the magnetic field, Φ is the magnetic flux linked by the contour, the time derivative includes variations in flux (as seen in the observer’s frame) due to changing magnetic field (giving the Maxwell-Faraday law of induction) and due the contour motion (giving the motional emf Faraday law of induction), and the minus sign along with other conventions gives the direction of the emf in the contour. a) Amp` ere’s law b) Faraday’s law of induction c) Gauss’s law d) Gauss’s law for magnetism e) Lenz’s law

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
