Cook An Egg Over Magnets - And Other Interesting Induction Heater Stuff.. 

Here it is, the first video of the series converting the garden train to maglev.

If you flatten the copper pipe a bit to give it a larger surface area at the bottom and make it into an arc to cover as many of the magnets as possible until the drag becomes too much, you might not even need a heating plate at all! It would also reduce the amount of magnets needed for the full-scale heater as you could get more energy from fewer magnets by covering more of the them. I'm really enjoying this project, thank you for this video

Instead of having the sail self furl, as the speed increases you want to bring the magnets and heating plate closer together, so you get more drag, which slows the windmill. You could use a mechanical governor for that.

This is basically how demagnetizers work so it is no surprise it demagnitized your wrench. Rapidly changing magnetic fields disorganize the magnetic field of the iron. dont put credit cards anywhere near this, it will break em.

* edit * as pointed out, an eddy current break

Make a copper coil that sits above the entire magnet ring. Flow water through it. The magnets will have more surface area to heat it.

The egg on toast was absolutely the best part of this video. I remember the comments saying that it would never work to heat up anything useful, and here you go and make a delicious snack. ha ha ha ha!

I find your videos so easy to explain such a complicated science, I am sorry I can’t give you any constructive advice, because I am not clever like you, but be assured, watching your videos is very satisfying.

I think the thing we learned is that crowd sourcing directions is not effective.

I 100% admit my ignorance of how either magnets or induction heating work. Thank you for building this interesting gadget.

The drag isn't a bad thing. The amount of power you produce as heat is going to be

The curved pipe design is really clever. Nice work! Looking forward to seeing where you end up with it

"In this house we obey the laws of thermodynamics". Seems like you are exactly correct, it's possible to make the system more efficient material wise but not energy wise. The amount of heat generated will be equal to the amount of energy in rotational force lost. Making something that heats up more/quicker will impart more drag on the system. The curved pipe idea is a good balance that would be easy to make self regulating.

One of the best examples of step by step engineering out there! My science classes live it!

What a great video Tim, love how you take all the information you gather and then do what you want and or think works best for you. Good job on that egg cooker.

Firing magnets into the next county was a good one XD

I love your videos, just on the verge of being eccentric but at the same time teaching me things I don’t know in an easy (for my brain) to digest.

I love seeing Bolesławiec dishware in the wild. Very cool project!

smaller magnets over the same circumference would result in more magnetic flips

That's a lot of work to just make a snack. 😄 Seriously, you have explained induction cooking to me and I now know that it works with aluminium, which I didn't realise. I love your methodology. 😊👍
