Read the wording for your board, then hide it and explain adding fields of turns in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Each turn carries the same current the same way round, so where the turns sit side by side their fields point the same way inside the coil and add together.
Each turn contributes a field and the contributions add inside the coil, so the same current produces a much greater magnetic effect.
