Definition of Force on a current-carrying wire
Check what you remember
Read the wording for your board, then hide it and explain Force on a current-carrying wire in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
F = BIl when the field is perpendicular to the current, and the force is perpendicular to both the field and the current.
