Magnetic field of wires, coils and inductors - physics behind induction heating 

I'm working on a solution and probably gonna redo this piece. As of now, I have just switched to a quality voiceover for most of the video as you can see in the newer ones. I did test a clip-on microphone ( can hear in intro of newer videos) - it is better than the audio here, but still nowhere near as good as the voiceover. And as you said, I will also need to change the room.

Yes, I'm planning to redo this video. Though, it will need more than processing existing audio ( I post-process all my audio with audacity for 2020 videos). In this case, the main audio was simply horrible. The microphone was far and a room full of reverberation sources. As for now, I mostly stick with a voiceover which I'm happy about quality ( for example can check the newest video). For better talking into camera shots I started using a lavalier microphone. It is an improvement, nevertheless, voiceover is still superior.

@@MHDTechnologyLaboratory That's great to hear! I should've considered the age of the video. Your content is very impressive, thank you for generating it for a public audience. Do you ever take requests for video topics?

@@Mrchingchingdingding I haven't had many requests. I have a list of future topics from which I choose what I work on. If you make a request you might get into that list given the topic fits some of my criteria.

​@@MHDTechnologyLaboratory I was wondering if you would consider doing a video on the application of chirped pulse amplification (CPA) on MHD-acceleration. I've heard of CPA on being utilized in other types of accelerators such as with muon generators and muon-catalyzed plasma-fusion generators. Yet nothing of their use in plasma physics, especially in MHD-theory derived applications. I've also seen this use case to generate pure heat through extremely high pressure induction that could be used in MHD thermal generators utilizing the Brayton Cycle: aip.scitation.org/doi/full/10.1063/1.4804200 . Long-term thermal storages systems are becoming more popular as a future alternative to electric batteries or chemical redox-flow batteries, yet it seems like the I haven't heard any news of improvements in the design of MHD generators despite the improvements in other fields that inform MHD experimentation. What sort of impact have advances in these other fields made recently in MHD-related areas of research that you know of? I find that these are all extremely fascinating applications of MHD physics, but what does an experienced researcher like yourself feel about the current development of your field? Are you familiar with these particular research topics on a firsthand basis?

@@MHDTechnologyLaboratory This slide, despite being from 2006, is one of the few resources I've found in which a renowned researcher takes the time to describe the current state of the field: ocw.mit.edu/courses/nuclear-engineering/22-012-seminar-fusion-and-plasma-physics-spring-2006/lecture-notes/mhd.pdf I'm including this to provide more context for my earlier questions. I guess I'd be curious to know if you have any videos that might include some of these topics and contemporary research in MHD physics.

Because heating is very quick and localized. Also steel does not conduct heat that well compared to other metals. He would not be able to do that with aluminum or copper ( 5x times and 10 times better conductors)
