Florida State University: Lenz's Law
Lenz's Law is defined and demonstrated with an interactive Java applet that shows the relationship between field lines of a magnetic and a conductor ring.
Georgia Department of Education
Ga Virtual Learning: Electromagnetic Induction
In this interactive tutorial students will learn about a magnetic flux, induced current and how to apply Lenz's Law.

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...

Teach Engineering: Whose Field Line Is It, Anyway?
Students teams each use a bar magnet, sheet of paper and iron shavings to reveal the field lines as they travel around a magnet. They repeat the activity with an electromagnet made by wrapping thin wire around a nail and connecting...

Com Padre Digital Library: Open Source Physics: Electric Generator Model
An electromagnetic induction model that simulates an electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter.
Science Education Resource Center at Carleton College
Serc: Electromagnetic Induction Demonstration
Students 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 coil of...

Ck 12: Lenz's Law
[Free Registration/Login may be required to access all resource tools.] Lenz's law is explained and demonstrated. It states that a magnetic field is produced in opposition to an induced current.

Com Padre Digital Library: Open Source Physics: Faraday Disk Dynamo Model
This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

Khan Academy: What Is Faraday's Law?
Do you know how to induce an electromotive force? This reference page will help you understand why Faraday's law mean and how to use it.

Creative Science Centre: 6 Generators
Apart from the piezo generator, all of these generators are based on the same simple design, where magnets are rotated near to coils of wire (Faraday Induction). There is no coil switching so these are AC generators. On magnet movement,...

Ithaca Hs Ny/electrical Generator Ac or Dc/applet
What a lovely little applet! You can speed/slow it, change it from AC to DC, plot the voltage as it rotates, change direction, control other information. Real neat.

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...
