This is a great video overall, but in my opinion a pretty poor explanation of the direction of a magnetic field around a coil. You said that, 'for a coil, the magnetic field goes in the same direction as the current'; but this is not always true (in fact, in this very question, it is not true) - it depends on the way that the coil is 'coiled'. If the current travels away through a coil in a clockwise spiral viewed from one end, this end is the south pole. But if the current travels away in an anticlockwise spiral, it's the north pole. When they say 'current from E to F', they mean straight through the ammeter, not all the way round the circuit, which explains how your explanation gets the right answer although the logic is wrong. But like I say, still a great vid so thank you.
Waste of 2 and a half hours - the explanations are longed out and unnecessary - it seems like you're trying to make the video longer for a few extra ads.

stop hating in the comments man, good video like the clear explanation
Getting that last minute revision in (I’m so cooked)
Why do you spend 5 minutes to explain a 1 marker
shit's genuinely hard

Same thoughts, scienceshorts has these videos but they're only around 50 minutes long for an A level paper. 2018 isn't available on his channel though
@@theredstonebuilder1120 yh ikr tried finding 2018 but this was only one I found. Gl all for p2 2024.
@@theredstonebuilder1120 yeah i literally came here because he didnt do 2018 for some reason
@@mehrazsaif6230 it is there but "unavailable" cos I think AQA copy striked him or smth, stupid exam board tbh
@theredstonebuilder1120 oh yeah he was saying about how he got copyright striked one time for showing the paper, must've been 2018 then
very helpful
