I can never remember LHR and RHR, so I find these a useful aide memoire

Hand-drawn diagram of magnetic field patterns: field round a conductor shown as concentric circles around a current into the page; coils and poles showing field lines in two coil cross-sections; force between conductors with parallel currents attracting and opposing currents repelling.
