B How Do Oscillations and Particles Interact in Electromagnetic Fields?

[nrckls]

For an upcoming presentation I am looking for a topic which covers both the field of oscillations/waves and particles in electromagnetic fields.
Do you have any interesting ideas for a possible topic?

Many thanks for your help in advance!

Welcome to PF.

The operation of the magnetron in a kitchen microwave oven.

Linear accelerators

Travelling wave tube amplifier - direct interaction between an electron beam and a slow wave helical structure which transfers energy from the electrons to power down the helix.

What academic level is this for, and how long is your presentation meant to be?

I am in my last year of school (12th grade in Germany) and the presentation is supposed to be about 10 minutes long. It is for my oral examination in physics (called Abitur, like A-levels in England or finals in the USA)

If you can make sense of this wiki article then there's enough there for a short presentation on the TWT. Ask here for a 'translation' of the more obscure bits but it really is a very straightforward device to get the idea of.

How about describing the cathode ray tube?

Where do the 'waves' come into it - except for the oscillating magnetic field and the deflection? I guess that, bearing in mind the level of the exercise, the idea of an oscillating field and scanning would be enough for a useful ten minutes of talk.

I'll have a look into it, thanks
