Science of Electricity – How Winding Affects Voltage Lab – Teacher

Summary

Teacher guide for an activity where students wind copper coils, move a magnet through them, and measure how the number of windings affects the voltage produced by building a hands-on model of electromagnetic induction and generator operation. Includes the full procedure, a lab rubric, and an answer key for all analysis questions. Designed for groups of 2 to 3 students, it works well in a middle school or high school physical science or energy unit covering electricity generation.
