In this activity, the students will complete the grand challenge and design an electromagnet to separate steel from aluminum for the recycler. In order to do this, students compare the induced magnetic field of an electric current with...

This lab was designed to have students test the factors that determine how much current is induced in a circuit when area of the circuit is changed. This lab is a quantitive lab that supplements the lab on magnetic flux.

This lab was designed to have students test the things that can induce a current in a coil of wires. This lab is a purely quantitative lab.

Complete this model of a Faraday loop by adding the equations to explicate a conducting loop in a constant magnetic filed.

Change the size and orientation of a conducting loop falling out of a region of uniform magnetic field. Then, the data is plotted on an interactive graph.

Easy-to-read information and an illustration of an "electromagnet," a type of magnet in which the magnetic field is induced by the flow of an electric current.

Keith Richards and Eric Clapton owe their fame and fortune (in part) to electromagnetic induction. (Java tutorial)

In this interactive tutorial students will learn about a magnetic flux, induced current and how to apply Lenz's Law.

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...

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...

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.

Learners 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...

[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.

This simulation demonstrates a rotating conducting disk in a magnetic field which produces a current or a self-exciting dynamo.

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.

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,...

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.

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...
