Hello! Hi and hey, today's video is on Induction Heating, if I sound sick it's because I am *cough* anyways, thanks! Leave a comment, I appreciate you guys :D

coming from someone with a with a BS in engineering, even through all of my various electrical E. classes that's the best, most concise explanation of induction I've ever heard... Bravo

love our videos, and your zvs driver video was very helpful btw. One correction, you can technically inductively het any metal, its just easiest with iron due to how easy it is to induce large eddy currents in it compared to other fero or paramagnetic metals. In the case of diamagnetic materials like copper of aluminum the currents simply flow in the reverse to what they would in a para or feromagnetic material. As well, it will take a lot stronger eddy currents to heat up more thermally and electrically conductive metals like copper as they will heat up less for the same amount of current and will dissipate that heat to the entire metal body faster than iron. I am 95% sure of this explanation, but if anyone has any corrections to this feel free to share them.

Awesome video and thanks for the shout out man! One thing though, non magnetic metals like copper and aluminum do indeed heat up with induction. Heat through induction is generated by eddy currents flowing in the conductive material AND because of the heat generated by hysteresis in magnetic materials. Since copper is not magnetic, it is heating at a rate that is directly proportional to the resistivity of the metal(which is pretty low). Most people think induction only works with ferrous and/or magnetic metals, but that is not the case. Copper will heat up with an induction heater, but much slower because it is not magnetic and has a lower resistivity than steel. Dropping the magnet through the pipe proves this as it shows the copper does indeed react to the changing magnetic field. With 1000W, I have boiled copper traces off of PCBs with my induction coils. In fact anything that is conductive will be heated through induction including the human body. MRI machines, which produce extremely strong magnetic fields, actually do heat up the human body a bit throughout the scanning process due to the nonzero conductivity of human tissue. Graphite is great example of a material that is neither a metal nor is magnetic but is amazing a turning the energy from an induction heater into, well, heat. Graphite is known as a susceptor and is used in microwaveable food package as a crisper like in hot pockets sleeves and popcorn bags. Watching the lithium battery explode in my video also is a good example of this as nothing in the battery is magnetic. Thanks again and keep up the great work! Feel free to message me with questions about induction heating any time.

dude you are a real world MacGyver. I use your videos all the time in college

[mo_arrows]

Most YouTubers try to stretch their videos to 10 minutes. It seems like you try to cram your videos to less than 5.

As a professional electrodynamacist I approve this

[nobleofftrack]

This channel is growing fast! I remember congratulating you on 60, 000 subs and now it's almost 70, 000.

[TheBayon]

You really know how to make me feel dumb. Amazing video series. I have just a basic understanding of electricity. Watching the projects that you do inspire me to do more. Thank you so much for your tutorials. I am still scared as all get out of the possibility of being electrocuted but with some common sense and proper protection I believe that I can reproduce your experiments. Once again. Thank you.

Your talking may be too fast for some people, but I think it's perfect. I honestly wish teachers and people in general would get through a lesson or a topic as efficiently as you do. Good job!

Brings me right back to AC/DC circuitry in college.

For the people with the problem of him talking too fast, click on the gear in the bottom right hand corner of the video and change the speed to .5 or .75x. I appreciate the speed in which he speaks. Update: I tried slowing the video down to .5 and I have to say, I think I prefer the videos that way. He sounds extremely drunk, and it's very entertaining, - especially around 1:12.

I subbed because I found another great engineer on youtube

[ChevisPreston]

I'm chem Engi and don't completely understand all of these circuits, but damn are they cool and interesting. Keep up the vids.

[MrAndrew]

smart man. you and Ben and builds should do a collab. definitely think you have some cool projects!

[pavphone]

The most important question is: Can you heat up a knife to 1000 degrees Celsius with it?

[codywelsh]

so I saw a video on how to make a mini hydrogen generator. But didn't really understand the use or importance. figured you could help explain and or give a real world example.

[TheDoctorPretzel]

Would love to see your take on a rail gun :D

[csnakeification]

I always learn something new everytime I watch your videos.good stuff for sure...

[BrutalProductions]

dude its like u know what im thinking, was looking at something like this yesterday and wanted to build me one LOL

[dirkbruere]

Put a polypropylene capacitor in parallel with the coil and drive it at the resonant frequency. Far more efficient if you can keep it on resonance as the metal is put in the coil
