Transcript:
(00:03) a little while ago I built this thing it's a disc with 40 magnets arranged around the rim with a North Pole of every second one facing upwards it was an experiment to see how effective it might be at heating water if it was connected to a large windmill now I don't have a large windmill yet so I used my pillar drill as a standin and yes it did heat up nonferrous Metals just by holding them close to the rotating magnets phenomenon called induction the alternating magnetic flux causes the metal to heat
(00:44) up without any direct physical contact it's really very interesting isn't it so the metal got hot and that heated up the water inside it and the faster the magnets spun round the faster the metal heated which is all very exciting but in a real windmill setup as I hope to build really fast spinning Parts could be potentially dangerous and of course they'll wear out so I went back to the suppliers of the magnets first for magnets.
(01:21) com and they kindly sent me a few more magnets so I could build this thing my absolutely huge spinning magnet induction heater how cool is that first four magnets.com have all sorts of magnets I'll put a link to them in the description thank you very much to them too now there are 100 neodium magnets in total set in a sheet of MDF so now each revolution of the new disc moves 100 magnets past any given point on the rim each time so without increasing the RPM the number of flux flips jumps by 250% all right then so that's what will
(02:15) happen but how will it affect the outcome that's the exciting experiment that I'm setting up here I made all the holes just a little bigger than the last time because I want wanted to leave room to set each magnet in some sort of waterproof seal cuz they don't like water at all now I started with varnish because it's runny enough to soak in and then spent an afternoon wrestling with the magnets they are vicious Little Things if you try something similar be very careful okay they all want to stick together and
(03:10) they don't want to be separated at all they will hop out of their little holes and fly across the board to get back to their friends and they are very strong and Incredibly fast so I came out scarred and blooded um and a couple of magnets were broken ended up but in the end they are all where I wanted them to be so I had to hold them all down individually while the resin under them went off then I added more resin lots more resin to hold them in permanently and properly I also managed to glue the disc onto the wheel hub which wasn't really
(04:15) the plan at all I don't know how that happened thank you Ashley [Applause] [Music] there's lots of weight in the disc now which means it takes a long time to spin up to speed and a long time to slow down again inertia how are you that's a good thing I think probably and this is my new arm bracket with hinge so I can support the heating element at whatever height works best it's quite a solid and lumpy heavy
(05:21) bracket cuz I don't want anything coming or drift near this thing once it's going I vanished the whole thing a couple more times hoping it will be damp resistant at least I even balanced the disc as best as I could just adding a little weight on the Lighter Side till it stopped at random places instead of in the same place each time now there was a lot of discussion on the best sort of heating element to use this time I'm trying a long length of 1in copper pipe mostly because I had it already I hope it's big enough so the
(06:13) water isn't restricted inside oh kinky but not too bad [Music] and it certainly works the water gets warm inside though it's hard to know how well it's going to work until the whole system is made so here's a bucket with tank fittings added with 3/4 in plastic pipes connecting everything
(07:21) together hung from the ceiling obviously the idea is that the cold water at the bottom of the circuit will be drawn up to replace the heated water over the magnets because that heated water should rise up through the pipe to the bucket where it should stratify into layers with the warmest at the top the coolest should be sucked slowly back down the other [Music] pipe so let's try it shall we the Water started at 13° C and I put 5 L into the system and spun up the disc
(08:36) [Laughter] now you will notice immediately that there is no insulation anywhere and I think that's the big factor in what happened the temperature Rose very quickly which was good after all that's quite a bit of water to heat up but the rise in temperature peaked very quickly too so it only Rose about 10° in about 10 minutes but then I guess it was cooling down just as fast as it was being heated up heat was being radiated off the whole system so it didn't get any h…

Based on the transcript you've provided, here are some instructions on how to create a magnetic induction heater using spinning neodymium magnets:
1. **Materials Required:**
- Neodymium magnets (at least 100)
- MDF sheet
- Varnish
- Resin
- Copper pipe (1 inch diameter)
- Plastic pipes (3/4 inch diameter)
- Bucket with tank fittings
- Wheel hub
- Arm bracket with hinge
- Pillar drill (or large windmill for final setup)
2. **Assemble the Magnet Disc:**
- Arrange the neodymium magnets around the rim of a disc made from MDF. Ensure every second magnet has its North Pole facing upwards.
- Drill holes into the MDF sheet slightly larger than each magnet to accommodate a waterproof seal.
- Use varnish to soak the MDF, making it damp-resistant.
- Carefully insert the magnets into each hole. Be cautious as they tend to stick together and are very strong.
- Apply resin to secure the magnets permanently in place. Ensure each magnet is held down until the resin sets.
3. **Attach the Disc to the Wheel Hub:**
- Carefully glue the MDF disc onto the wheel hub.
- Balance the disc by adding weight to the lighter side until it stops at random places, ensuring smooth spinning.
4. **Build the Heating System:**
- Create a support bracket using an arm with a hinge to position the heating element at the desired height.
- Use a long length of 1-inch copper pipe as the heating element. Ensure the pipe is large enough to allow water flow without restriction.
5. **Set Up the Water Circulation System:**
- Connect the copper pipe to a bucket using 3/4 inch plastic pipes with tank fittings.
- Hang the bucket and pipes from the ceiling, creating a closed circuit for water circulation.
- Ensure that cold water at the bottom of the system can replace the heated water, which should rise through the pipe and stratify in the bucket.
6. **Testing and Insulation:**
- Fill the system with water (e.g., 5 liters at an initial temperature of 13°C).
- Spin up the magnet disc using a pillar drill or a motor.
- Monitor the temperature change. Note that without insulation, heat will radiate away quickly.
- To improve efficiency, wrap the system in insulation to retain as much heat as possible.
7. **Safety and Adjustments:**
- Be cautious when handling magnets as they can cause injury if they snap together.
- Make necessary adjustments to the system based on initial test results, such as adding insulation or adjusting the water flow.
These steps outline the basic process described in the transcript. Remember, this is an experimental setup, so take appropriate safety precautions and consider improvements for efficiency and safety.
does it say what type of power of heating it gives off? Like for how big an area? And how long it might last? And you always need a power source to run it? ("Spin up the magnet disc using a pillar drill or a motor.")
The transcript does not provide specific information about the power or heating capacity of the magnetic induction heater. It mentions that the setup heated water by approximately 10 degrees Celsius in about 10 minutes, but it does not specify the volume of water or the area that could be heated with this arrangement.
The longevity of this setup is also not provided in the transcript. The durability would likely depend on the quality of the materials used and how well it's maintained.
As for the power source, the transcript describes using a pillar drill or a motor to spin the magnetic disc. This implies that some form of external power is necessary for the operation of this induction heater. Without something to spin the disc, there wouldn't be the necessary movement of the magnets to generate the changing magnetic field that induces heating. So yes, a power source is necessary for this setup.
Why is this considered "huge" in its implications?
The term "huge" in this context likely refers to the size and scope of the project - using 100 spinning neodymium magnets is a large undertaking, particularly for a DIY project. The potential implications of this project could be considered "huge" in that it demonstrates a method of generating heat that does not require direct contact with a heat source or traditional fuel.
This could have implications for renewable energy, as the system could theoretically be powered by something like a wind turbine (as the creator originally intended). If scaled up, this system could potentially be used for heating homes or other larger spaces, although the transcript does not provide enough information to confirm this.
However, it's important to note that this project is experimental and the efficiency and practicality of scaling it up for broader use is not discussed in the transcript. It's a fascinating concept, but more research and development would be needed to determine its potential applications.
