yes agreed it was quite easy compared to last yr, cept didnt finish last parts of 10 b) or the last part in 9 that stupid beam question!!!! now i have got ext on wednesday and not looking forward to it!!:(
torque is opposite the magnetic flux
so when magnetic flux is max (perpendicular) torque is minimum, cos 90=0
but when magnetic flux is min (parrallel) torque is max cos 0=1
if you draw a diagram it helps... when the coil is perpendicular, heaps of lines hit it, therefore magnetic flux max
but...
