The EJS Electric Generator Model shows a simple electric generator made from a conducting loop rotating in a uniform magnetic field and connected to an ammeter. The model shows a plot of the magnetic flux and induced current. 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 Electric Generator 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_Generator.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.
Please note that this resource requires
at least version 1.5 of
Java (JRE).
The EJS Generator Model shows a simple electric generator of a loop rotating in a uniform magnetic field. A plot shows the current (in ?A) and flux (in arbitrary units). Users can examine and change the model if they have Ejs installed.
4G (9-12) #5. Magnetic forces are very closely related to electric forces and can be thought of as different aspects of a single electromagnetic force. Moving electric charges produce magnetic forces and moving magnets produce electric forces. The interplay of electric and magnetic forces is the basis for electric motors, generators, and many other modern technologies, including the production of electromagnetic waves.
