The Faraday Loop Changing Field Model shows the induced emf in a changing external magnetic field. You can control the frequency, magnitude and type of variation in the external field as you would in the laboratory when using a function generator to produce current in a large coil. You can also change the size and orientation of the conducting loop. If Ejs is installed, right-clicking within the plot and selecting "Open Ejs Model" from the pop-up menu item allows for editing of the model.

The Faraday Loop Changing Field model was created using the Easy Java Simulations (Ejs) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double clicking the ejs_em_FaradayLoopChangingField.jar file will run the program if Java is installed.  Ejs is a part of the Open Source Physics Project and is designed to make it easier to access, modify, and generate computer models.

Please note that this resource requires at least version 1.5 of Java (JRE).
