Using the BIGS simulation experiment in app form, you can simulate the behaviour of an electron beam in crossed fields. It is possible to simulate:
o the behaviour of an electron beam in an electric field;
o the behaviour of an electron beam in a magnetic field.
o the behaviour of an electron beam in crossed fields,
o the creation of cycloid paths by the electron beam,
o and to determine the specific charge (q/m) of an electron (i.e. the measured values shown in the app correspond to those of the real experiment).

This app is a learning aid for the examination topics "electron beam in crossed fields", "moving charges", "function of a cathode ray tube" and "Wien filter".
It can be used both in lessons and in revision for exams.

The simulation has been designed by BIGS as a self-explanatory program. However, user guidance is also available. Within the app, users can switch between the simulation and a worksheet intended to provide an even better understanding of the physics underlying the simulation. Users can also download additional work materials from the BIGS server using the "More" button. The materials developed by BIGS include work sheets and assignments.

Together with the worksheets, the simulation guides users through to determining the specific charge (q/m) of an electron, including writing a report on the experiment. The assignments are intended to allow users to test the knowledge they have acquired.

The learning aid has been successfully tested in advanced physics courses at German high schools such as Giebichenstein Gymnasium Halle.

The "Electron beam in crossed fields" app is intended to provide support for students who wish to develop their knowledge independently.

With a click at the button “More” you can get more worksheets and exercises, but you will not get here solutions and educational notes. That you will get with the version (T).

This app is usable in combination of interactive whiteboard and tablets.

New features

BIGS reacted with the version on the new device generation of tablets and smartphones.
