The electrons in a vertical magnetic field circulate around the field lines, if they are injected in a horizontal plane.

I observed this in my simulation program.  Everything normal, in accordance with Lorentz's law.

However, when I created an electric field by placing two charged rings in the simulation space, the electrons, still move in similar little circles, but also move in a “big circle”… And the radius of this big circle seems to be, more or less, independent of the magnetic and electric field, and it also does not matter, more or less, in which direction the electrons are injected.

Curious…

Does anyone know this behaviour?

Has anyone observed this in any real experiment?

I do not know if this could be usefull for something, but just wanted to share this with you.

Best regards,

It would be more useful if you included the source code of your simulation..

It does not take into account relativistic effects..

 

Charges in a penning trap show three separate motion contributions. Your configuration has a similar setup.

 

The resulting ion motion in a Penning trap consists of three independent eigenmotions, two in the radial plane and one in the axial.

Interesting, thanks. +1
