Falling Bar in a B Field Model
written by Armando Pisani
The Falling Bar in a Magnetic Field model displays the non-uniform motion of a conducting bar as it slides along a vertical U shaped wire with resistance R.  The apparatus is imbedded in a magnetic field that is B perpendicular to the plane of the bar.  The Faraday-Neumann-Lenz law for electromagnetic induction produces a motional emf and an electric current that interacts with the external field.  The motion of the bar shows that the bar's velocity exponentially approaches a terminal value.

The  Falling Bar in a Magnetic Field model was created using the Easy Java Simulations (EJS) modeling tool.  It is distributed as a ready-to-run (compiled) Java archive.  Double click the jar file to run the program if Java is installed.

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