Different right hand rules?

Okay so I came across this older question about a positive ion in a velocity selector (perpendicular magnetic and electric fields) when studying for SQA AH Physics which uses Higher knowledge - aka the right hand rule - but when I use the right hand rule I was taught it’s giving me the wrong answer? I was always told to flip or use your left hand for a negative charge and use right hand for positive but by using my right hand i get the opposite answer.

I was taught Thumb is the Thrust (force), First finger is the magnetic Field, Second finger is electron flow (current).

But when I googled to double check I was met loads of different versions. Does the version I’ve learned only apply to a wire or certain conditions?
