Definition of Left-hand rule and conventional current
Check what you remember
Read the wording for your board, then hide it and explain Left-hand rule and conventional current in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
First finger field, second finger conventional current, thumb force; for a negative particle the conventional current is opposite to the particle's velocity, so the force reverses.
