Electromagnetics | 11-2: Electromagnetic Induction | Purdue University

Watch how electromagnetism works in this hands-on experiment guided by Purdue University Professor of Electrical and Computer Engineering, Michael Melloch. This demonstration, inspired by Michael Faraday, uses a magnet and two coils, one with 100 turns and the other with 25 turns, to reveal the properties of electromagnetic induction. You'll see how the reading on the ammeter changes as the magnet moves in and out of the coils, providing an understanding of magnetic flux's relationship with time, coil turn count and resistance. From this experiment, Prof. Melloch will lead to the formulation of Faraday's law of electromagnetic induction—highlighting the link between flux change, time, and current, and how it is applied in the context of electromagnetic induction.
