i still can't seem to understand how to use FLHR to deduce the charge of a particle in particle detectors. I know that positive particles move in the direction of current yet I still end up making the same mistake on every past paper I solve.
anyone care to explain please?

And what mistake is that?
people can get confused about what the direction of the particle is when the track is spiralling like that - you just need to pick a single point on the path and see which way the particle is being accelerated at that point... e.g. pick a point where the track is going horizontally left to right and see if the position of the particle goes up or down further along it's path.
