A teaching tape for SR-13, electron dynamics and force conventions
electron work and deflection
Teaching tape demonstrating mass coefficients, work, kinetic energy, and deflections for a relativistic electron.
Open SR-13 with these settings
Where it starts
| Setting | Value |
|---|---|
| Electric field X (electricFieldX) | 0 |
| Electric field Y (electricFieldY) | 100000 |
| Electric field Z (electricFieldZ) | 0 |
| Magnetic field X (magneticFieldX) | 0 |
| Magnetic field Y (magneticFieldY) | 0 |
| Magnetic field Z (magneticFieldZ) | 0 |
| Initial speed (v/c) (initialSpeed) | 0.6 |
| Initial direction angle (initialDirectionDeg) | 0 |
| Integration interval (integrationInterval) | 2e-9 |
What it changes, and what to expect
Set Initial speed (v/c) (initialSpeed) to 0.6 changes what the run starts from
electron-dynamics-0.6c
At 0.6c, the electron has gamma = 1.25, transverse mass 1.5625m in Einstein's 1905 convention and 1.25m in Planck's 1906 convention. Both conventions yield identical observable deflection radii.
These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open SR-13 with these settings: the link opens it with them already in place. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
