Not bad.

Fairly easy overall, just a few odd questions at the beginning :smile:

Lol what did u get for the magnification calculation I got 0.4, I think I got the diagram fine?
0.005N for the moments one
60 turns of coil for the transformer one

oh and magnification 0.5

I had no idea on that one - i did a straight line going horizontal... probably wrong but at least it was only one mark!

does anybody want to do a mark scheme for it?
basically random points increasing gradually but all under 20

shape allowed to hang freely on a nail on a pole thing (didn't put pole thing lol)

plump line (weight on a string) allowed to hang freely in front of it, draw a line where it hangs

repeat to get a second line from a different hole to see where they cross

The UMS better be incredibly low, because literally everyones saying it was hard! I know i got the moments wrong because of silly mistakes, got 0.5 for magnification but i had no idea what I drew!!
and umm it was step up because had more coils in the secondary coil but for the working out I had..I can't remember but i'm sure i got that right :P
Gonna check marks as soon at the mark schemes out ! :P
Really worried about this exam :s I couldn't do the moments and the magnification... Could anyone post a markscheme???
