Hi,
I've just cleaned up this page; I hope it's now somewhat decent. I'm sure it still needs some work, but as I'm still a relative newbie, I'm not so sure what else to add. I also think that several of the stubs that this page links to could also be deleted, but I'm not about to do that just yet. Sentinel75 07:01, 1 December 2005 (UTC)[reply]

The page states "drawbacks include the fact [...] if an induction cook-top is installed in a home and the owners wish to move, a choice must be made to either take the whole induction cooking set with them, or leave it all behind." How is that different from any other cooktop? Alephone — Preceding unsigned comment added by Alephone~enwiki (talk • contribs) 06:07, 24 March 2006 (UTC)[reply]

Levitation

I have seen in many youtube videos (so it's not fake) that induction, apart from heat, can produce levitation. But I'm not an expert on the matter, so I don't know if it's with all metals or just with some of them. This video is an example: http://www.youtube.com/watch?v=Q6Zrnv4OtbU The only thing I know is that they invert a couple of last coils to make it levitate. I think it'd be great to add a section about this, as it's really relevant for it's possible engineering applications.

Definition of Induction Heating

Definition as it is on the page is not accurate. Beside of metals other materials may be heated (graphite, molten solts, oxides, carbides etc. as well as ionized gases - plasma). I can provide more accurate definition that covers all cases of induction heating. Please advise. Nemkov

Agreed. Induction heating can, in principle, be used with any highly coductive material. This should be changed/updated. Lesotho 02:08, 15 March 2007 (UTC)[reply]

Photo is not of induction cooktop.

The photo appears to be of a conventional glass/ceramic cooktop, and not an induction cooking surface. An induction cooking surface will not glow, and in fact, won't even get hot without an appropriate container placed on it. D3z (talk) 20:35, 1 January 2008 (UTC)[reply]

Hi

I used to work in induction heat-treatment application development and modelling for a decade - so i know something about it - but I have been out of the game for a decade - so could be said to be independent.

I would like to add something here - how should i go about it? —Preceding unsigned comment added by 203.166.123.34 (talk) 02:20, 18 April 2008 (UTC)[reply]

Simple explanation of Induction Heating

Pls could anyone provide a simple explanation for the process. I guess the definition given is correct and precise / but precise to the point where it is difficult to understand even for me who hold a university degree in electrical engineering ;-) I am after something like Induction Heating explained for kids ... or for the standard family who is considering an induction stove. Something like (it needs to be edited!!! and maybe it is even incorrect?!) IH applies the fact that electrical current heats the material it passes through due to resistance ( this mechanism is used e.g. in an electrical water heater). The higher the current the more heating. The bigger the resistance the more heating. In IH AC is used. For an IH stove the bottom of the pot is heated and this heat is transferred to the food in the pot just like in an electrical or gas stove, but the method of the heating of the bottom is different. The electrical current in the bottom of the pot is generated not by having two electrical poles but by creating a magnetic field in/around the bottom. The magnetic field is created applying AC to a magnet located under the pot. I.e. ordinary AC voltage is applied to a magnetic material which in turns generate a magnetic field around it. This field generates an electric field in the bottom of the pot which becomes hot due to electrical resistance. The food is heated normally. A drawing would also be beneficial!

Inductive heating of gas (plasma)

There should be a section about inductive heating of plasma. -- Dougher (talk) 16:25, 29 October 2012 (UTC)[reply]

Couple of issues

1. In section: "Core type furnace" "...contains the charge to be melted in the form of angular ring" Should that be "annular" ring?

2. In the table "Applications of frequency ranges", in the row 100-400 kHz, what is the application for heating "steel at 25 deg C with a diameter of around 0.1mm"? Gwideman (talk) 20:27, 2 January 2017 (UTC)[reply]

An issue?

There's a problem(I think) in the line were you say [ferromagnetic] you say it twice. DarthWikiVader (talk) 20:54, 28 January 2019 (UTC)[reply]

Done - thank you for pointing this out. I have restored the original content. GermanJoe (talk) 21:00, 28 January 2019 (UTC)[reply]
