In case of table top portable induction heater, metalic vessel(pot) (which is kept on the heater) is heated by eddy currents induced by the coil inside the heater. Pot heats because this eddy current in the vessel has nowhere to go. But if we touch the pot then this current has a path to ground through our body. Hence we should feel electrical shock. But we don't. Why ?
Answer
To get a current from the pot to ground, you must have a grounded power source connected to the pot. When the power source makes the pot positive with respect to the ground, current want to find a negative voltage return path thru the person touching the pot.
Your induction pot's power source is insulated from the pot, so it induces voltage difference between different locations in the pot, not between the pot and ground. It might be possible to measure voltage difference between two locations on the pot, but the voltage is probably too low to give a shock.
What Are The Slot Vents On The Side Of Microwaves For & What Do The Vent Or Do?
Yahoo! Ans
I have a table top portable microwave that sits on a table. The Sharp brand Carousel kind you buy from like Walmart.
Not an installed wall mounted microwave like in many custom homes. I am wondering what those vents on the side of the microwave emit or release. Please help. Thank you.
All in all , I ask that question because I just don't like the basic idea of my CD's being anywhere within a room or so away from the microwave spot. I am trying to preserve my original store bought CD collection for personal reasons. Copied & or backed up CD's onto blank discs or secondary devices are of lower quality & standards as the original studio recorded music store bought CD's. I don't think I want to back up my CD collection over a microwave oven paranoia dilemma. If people are saying that microwaves do not have any effect on CD's being outside of the microwave & being some distance away , I am comfortable with being told that I guess. Again , it's just the idea & knowing I used my microwave within a room away from where my CD's are currently located. Yeah , I admit I might be obsessed with my CD collection , but I spent so much money on them & it's no thanks to that damn MP3 generation these days that want their music cubical-ized into a p
My additional details got cut off. Oh well. Sorry.

Like any thing else that has vents, they are there to "vent" the machine.
Mot likely, to cool the machine. The machine is gonna generate heat as its being used, so, the heat has to escape some how. Otherwise, it's gonna stay trapped inside the machine and over heat.
Vents = exhaust vents.
What comes out of it? = hot air.
[Edit - after reading your additional info]
If you're worried about the microwave having some sort of affect on your CDs, you can stop.
The air coming out of the exhaust would not be hot enought to affect your CDs. Even the actual microwaves being emitted from th microwave itself will not affect your disks. The only way something would happen to your CDs is if you threw it in the microwave and turned it on (it would melt).
You should understand how a CD (or any digital disc works), so you won't worry so much.
Once a disc has been burnt (let's use an audio cd for example), nothing will affect the sound quality. The sound quality is the data that is burnt into the disk, and it's permanent. The actuala data is etched (burned) into the plastic of the CD. The marks made are tiny. We cant see all the marks burnt on the CD, but if you look at the underside of the CD, you can see the difference between the area that was burnt, and the area that wasn't. The data will remain unchanged as long as the actual disc is physically undamaged (scratched).
When you put the cd into the player, the cd player will shoot a laser at the under belly of the cd. The laser bounces off the reflective layer that's painted on the opposite side of the CD, and back to the reader. The laser passes through the clear layer with all tiny burnt marks made, and when it gets reflected back, the reader can read the actual data.
Sound quality on a cd depends on the amount of data there is for a given song. Usually, the more data there is for a song, the better the quality.
Tha said, there is nothing that can affect the sound quality of a cd after it has been burnt. The only way to degrade the sound quality is to make the disk unreadable some how. Otherwise, the only way to degrade the sound quality is to mess with the file before you burn it to the cd.
