# Electric and Magnetic Fields watch

1. Hi. I've missed quite a few lessons recently so please excuse the relatively simple questions.

I found a powerpoint on getrevising.co.uk and it says this,

The force on the charged particle due to the magnetic field is up, using Flemings left hand rule
The force due to the electric field will be down (as the positively charged particle is attracted to the negatively charged plate)
The magnetic force equals BQv
The electric force equals EQ (as E=F/Q)

I'm confused as to what this is referring to. Could anyone please explain? I'd really appreciate it.

Was there a diagram with this? The first two statements seem to be referring to a specific example...

There was a diagram of a S and N magnetic pole, and perpendicular to that was a positively charged plate and a negatively charged plate. So the magnetic field and electric field were perpendicular.
