Have you noticed that there are alot of the direction questions? i.e. for current with magnet going through coil
Kinda worrying me cause I havent seen that many in the 08-10 exams....and still not 100% sure how to do them
Really? I came across quite a few direction questions, I've been using the right hand rules a fair bit.
I just did Insight 2011 and that kept asking for directions (no pun intended).
The most common one is something to do with Lenz's law and how it flips. VCAA has been tending towards drawing the magnetic field, I guess that incorporates direction. I've seen a lot of the exams ask for direction in a multiple choice style.
There were also those compass needle questions. You'd think they'd have enough
insight to know read a compass.
Edit:
On how to do these direction questions, I just stick with the right hand grip rule, right hand slap rule and Lenz's law (if talking about current/emf/flux that has been induced) and that's gotten me through pretty much all of those questions.
