Faraday Disk Dynamo Model 1.0

Date Added: September 15, 2013  Visits: 244 


The EJS Faraday Disk Dynamo shows a conducting disk that rotates in a magnetic field. This produces a current (homopolar generator) and for certain configurations, it is a selfexciting dynamo. A selfexciting dynamo is the mechanical analog of a proposed mechanism to produce the earth and sun's magnetic fields. You can modify this simulation if you have Ejs installed by rightclicking within the plot and selecting "Open Ejs Model" from the popup menu item.<br /><br />The Faraday Disk Dynamo model was created using the Easy Java Simulations (Ejs) modeling tool. It is distributed as a readytorun (compiled) Java archive. Double clicking the ejs_em_FaradayDiskDynamo.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. Additional Ejs models are available. They can be found by searching ComPADRE for Open Source Physics, OSP, or Ejs.
