For 13a of electric power, I had the flux decreasing after R bc before then the coil is completely inside the magnetic field still. idk hahaha

i had this too?

Same here, because the question clearly said "experienced by the front end of the loop" or something along those lines

Yes same! Lol was too scared to say because I was pretty sure it was wrong. Maybe not

well we can lose 2 marks together if it's wrong lmao

Yes, you guys are right in regards to question 13b. My bad! I'll fix it now.

If I recall correctly shouldn't one of the multichoice questions in electric power be A (the one with the current or voltage graph when the rotor is turned by hand because if it is rotated by hand isn't it AC?

Anyone get this for the graphs?

Excuse the terrible ms paint skills ahaha

nah bc a commutator is attached, so AC is converted to DC

That's incorrect: within the first segment of the graph none of the loop has yet to enter the magnetic field, so the flux is zero for that segment.

I'm guessing you'd only lose 1 mark out of 4.
