Definition of Newton's third law applied to magnetic forces
Check what you remember
Read the wording for your board, then hide it and explain Newton's third law applied to magnetic forces in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The field exerts a force on the wire, and the wire exerts an equal and opposite force on the magnet, so the balance reading changes.
