Electricity/Magnetism Learning Activities

Supplier: ELWE LEHRGERAETEBAU KLINGENTHA

The exercise oscilloscope is placed at the Helmholtz coils so that its main axis coincides with the axis of the coils. A sawtooth-shaped voltage is applied to the deflection plates of the oscilloscope so that a smooth horizontal line appears on the screen. Let direct current pass through the coils at a preset anode voltage and adjust the intensity of the current so that the line is focused at one point. The specific charge e/m of the electron can be calculated from the measured values ​​of the anode voltage and the current through the coil.

Supplier: CORNELSEN EXPERIMENTA

Plastic rod with metal tube equipped with an axial and a radial 4 mm connection.

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.
