  • Electromagnetic Induction

    The field is perpendicular to the plane of the loop, such that the magnetic field lines pass through the loop. We will examine the interactions of the loop with the B field and the resulting induced EMF.

  • Faraday's law of induction: Example problem

    The induced emf is equal to E = - N delta (flux)/delta (time) = - N delta (magnetic field X area) / delta (time) When the external magnetic field B is changing, delta (magnetic field) is non-zero. Then, there will be an induced emf.

  • Which will not Induce an EMF in a coil of wire
