Other ways to explain rather than RH rule. (1 Viewer)

Is there any other ways to say a particle is negative instead of saying "according to the right hand palm rule".

This is in particular relation to cathode ray experiments wich flourescent display screen. I was to say the cathode rays were deflected by a magnetic field and they are negative. But I don't want to say "because of the RH palm rule".

The force is always perpendicular to both the direction of current and the direction of the magnetic field.

Instead of deflecting them with a magnetic field, use electric fields to deflect them, makes for a more sophisticated answer. Use 2 charged electric plates and if the cathode ray consists of negatively charged particles it will bend towards the positively charged plate (negatively charged particles are deflected in the opposite direction to electric field lines/ or simply possitive attracts negative).

oh this one was when the magnet was brought towards the zinc sulphide screen.

but thanks.
