Teach Engineering: Changing Fields
This lesson begins with an activity in which students induce EMF in a coil of wire using magnetic fields. Then, demonstrations on Eddy currents show how a magnetic field can slow magnets just as Eddy currents are used to slow large...

Pbs Teachers: Scientific American: 21st Century Medicine: Image Guided Surgery
Investigate the science and medical diagnostic uses of magnetic resonance imaging (MRI) technology. Perform experiments to observe how magnetic properties can be induced, and measure the force of temporary magnets.

Serc: Electromagnetic Induction Demonstration
Young scholars learn the relationship between the electric and magnetic fields. Specifically, they verify that a magnetic field is created in a current carrying coil of wire and a changing magnetic field can induce a current in another...

Serc: A Simple Motor/generator Demonstration for Use in Interactive Lecture
This apparatus is easy and inexpensive to construct and provides a clear and compelling demonstration of Faraday's Law of Induction and the Lorentz force. Two magnets are suspended from springs so that they are free to oscillate...
