Physics Exam 2 (End of Year) thoughts

[m@tty]

I don't know... wiki says that faraday's law states that:

The induced electromotive force (emf) in any closed circuit is equal to the time rate of change of the magnetic flux through the circuit.

No negative.. I always thought that Faraday's law only gave the magnitude.

hmm but if you scroll down it has the negative in his formula.

Even if I'm right, you put both so hopefully you get a mark. If you're right then I get 0 haha

[m@tty]

What?.. Why does the equation not align with the explanation.. No matter.. Argh, I trusted the MGS guy at VU. He said Lenz's law is Faraday's with the negative >.<

I reckon a bastard examiner won't see what I meant and would penalise me for what he perceives as hedging my bets xD

You'll be fine, even if you lose it, 87 will most definitely still be an A+!!

i'm sure faradays law outlined magnitude while lenz's law specified direction

I dunno if anyones mentioned this but the people that went to the VU PHYSICS LECTURE would have gotten a MASSIVE advantage if they listened to the guy...
he basically told us whats on the exam (he said that there was gonna be a 50% chance the xray/electron q was gonna on it and then told us about that diffraction pattern/similar wavelength) , and also a bunch of other stuff which i cant remember...

MGS guy?

DID ANYONE SAY OBSERVATION1 its wrong wrong wrong >: (

[Whatlol]

DID ANYONE SAY OBSERVATION1 its wrong wrong wrong >: (

i think its OB 2 , itute changed from 1 to 3. so who knows

[waack]

lenzs law does state that the emf is the neagtive gradient, no one is questioning that, BUT the question was asking about through the voltmeter so its irrelevant wat the voltage is doing in the loop it depends on the voltmeter i think they will excpet both

[Blakhitman]

It's observation 2 for sure hands down, will bet my left nut(ella) on it.

[waack]

+1

Um Geoff Davies ran the free VU lecture.

0.o he's my physics teacher, he's epically pro =/

I think he also told our calss in like Term 3 that Lenz's law is faraday's law with engative sign on it =/ then he told us that lenz's law = direction and faraday's law = magnitude later on.

Yeah, he teaches at Melbourne Grammar School (MGS)

It's observation 2 for sure hands down, will bet my left nut(ella) on it.

I sure hope you're right because I put down Observation 2 as well
