3. Using your text or a web resource, find an expression for Faraday's law. Using diagrams similar to Figure l, relate the induced emf, g, to the rate of change of the magnetic ux passing through the coil as the magnet rst approached, then receded om the coil. 4. For your rst run, click and drag (with either the mouse or stylus) to select the region that shows the potential changing as the magnet approached, passed through, and then receded from the coil. Enlarge this region of the graph. (In Logger Pro, choose Zoom Graph In from the Analyze menu; in LabQuest App, choose Zoom In from the Graph menu.)
