Induced EMF in a Coil of Wire Lab
Students use a simple set up consisting of a coil of wire and a magnet to visualize induced EMF. The students can move the coil, the magnet, or a second, current carrying coil. They observe the EMF produced on a voltmeter or multimeter as they perform these actions. Lab handout is included.
Electromagnetic induction is an important concept, because it is the fundamental physics behind how we produce the vast majority of our electrical power. It is also a difficult concept for high school students to understand. Through this hands-on activity, students will demonstrate that relative motion of a magnet around a coil will produce a measurable voltage, or EMF.
