I see, thanks for sharing this method, they don't teach it in my school. Probably because they don't teach anything and I have to google everything anyway. This doesn't destroy my pole method though. If I saw there is no flux, I would stop right there and never get to it. Anyway, this...

I'm not sure why no current would be induced, is it because the conductors now form a ring that induces an opposite current? If yes, I could represent it as 2 power sources, which negate each other. Not sure about this though.

Well It's still tehnicaly the same thing, right? It might not be best to treat it as a circuit, since voltmeters don't allow current flow(in theory), but I still believe it's ok to imagagine it as a battery. You can use a voltmeter to probe a battery and check it's Emf. An alternative way I...

So all I got wrong is how voltmeters work? I usually don't look for the direction of current when figuring out voltmeters, just poles. What confused me is that the metal ring is like a power source, so electricity doesn't flow from the positive pole to the negative, but the other way around. Is...

Update: I believe I've figured out what's wrong. It seems that voltage is actually positive when it goes into the + pole first. The reason I thought it was opposite is this picture: and some others, portraying the same thing. So, in the picture, are they just using the actual direction of...

I know this, the potential thing was defined in the task, not sure why. This still leaves me with the problem. The current flows counter clockwise, right? The agreed upon direction (+ to -) is generaly used in magnetism. So this is the flow: So shouldn't this give a positive value? The...

Homework Statement The problem is simple, all I have to do is draw a voltage / time graph. The black ring is a conductor, its inner surface area is 0.01 m^2. The magnetic field points upward, B = 4T. 2. The attempt at a solution I understand what I have to do, but I'm getting the wrong +/-...

Ok ,I undestand, Then i guess i did make the basic one, but it works good for me

Now I you wrote carbon carbonate and now I am confused.So I'm going to start over:This is how I got the whole thing I ask will it make copper cabonate, you say it will make just carbonate(even tho that doesn't really exist), i do it, i make copper carbonate , i heat it up it turns black(becomes...

I didnt check how pure it is , but since it turned to copper oxide(mixed with hcl to test) I conclude its pretty pure.

If someone is looking at this later,I tryed it and it worked great.Made rather pure copper carbonate until it ran out of electrolyte ( then copper hydroxide was made slowly).Turned to copper oxide nicely too

Allready did,I'm just going to use it for getting a small amount of pure sodium

I thought somebody had experience and could tell me this from experience, I tried making it a lot of time and it allways gets contaminated from the collapsing of my carbon electrodes. So before i find out if will stop when its done (so i know when its done) I won't go and find a power supply...

Sodium chlorate and some other stuff

So, when water is electrolysed NaOH is created,but since NaOH is an electrolyte itself how de we know that the NaOH doesn't start electrolysing too?
