Electromagnetic Induction Study Guide for Chapter 31 Outline 1. Motional EMF A straight segment of wire moving through a magnetic field experiences an . The induced EMF magnitude of the EMF is given by the formula   where is the length of the wire, is the velocity, and is the magnetic field. Problems: 1 2-3. Faraday's Law, Lenz's Law Magnetic flux is the similar to electric flux, but using the magnetic field:  BA Magnetic flux is measured T m , which are sometimes called (Wb). Webers A loop of wire experiences whenever the magnetic flux through the loop changes. induced EMF The magnitude of the emf is given by the formula:    (Faraday's law for ) The negative sign signifies that the induced emf the change in flux (which is called opposes Lenz's Law ). Problems: Answers: 18. 80. 18, 27, 29, 80 mA to the left T s   
