Core Material

Has anybody tried to build a core made with PVC pipes filled with ferrofluid, but more importantly, would it work? I wonder.

It would be interesting to see.

Core Material

I wasn't saying put a magnet inside of the transformer, but if that design sparks your interest, go for it.

Just to make sure that we are clear on what I was conveying. See http://www.energeticforum.com/attach...7-17.30.44.jpg. Notice how I have curing magnets outside of the mold. These magnets are relatively large Neo's. However, they were still too small to align the magnetite domains to get a transformer effect (good mutual inductance between coils). Peter says the curing magnets must be as tall as that mold of magnetite resin that I have in the picture. Clearly, my magnets are underrated for the task. Therefore, magnetite was a poor option for my core and will be for you too if you don't use LARGE curing magnets. I have no idea how you would cure both the vertical and horizontal axises at the same time. Good Luck!

Well, that is interesting. Something to think about.

I think Thane just uses laminated steel cores.

If we could do this with coils in place we could run current through them and alien the magnetite this way.
Something to think about.

We need to figure out how to do this using spools so we can wind beforehand, good thread I like the concept.

Black Iron Oxide As Core Material



At present, black iron oxide powder seems to be cheap (20 lbs for $20), but that could change if demand for it increases.

I found it on ebay. 20 lb Black Iron Oxide - Fe3O4 - Used in thermite | eBay

Thanks for starting this thread and posting links to the videos on making the cores. I think your transformer concept is straight forward and makes good sense. I have been looking at this for a while and now that I know a good way to make cores I guess I can get started trying to replicate.

Mark III Generator

Thanks for the warning. I like Magnetite because it's cheap and you can mold it into any shape you want. Just build a form.

To incorporate a magnet in the design, I propose the Mark III Generator.



Best of luck replicating.

@Web000x,

Where do you see magnets in any of Thane's transformer schematics?

I don't. I apologize for the ambiguity of my post.

In the caption of Vidbid's drawing, it says that the cores can be made from magnetite. He references Peter Lindemann's "Magnetite Core Material". In Dr. Lindemann's lecture, he states that when curing magnetite one must use "curing magnets" to align the domains of the magnetite particles. I was simply talking about constructing cores from magnetite. It has nothing to do with Thane's observations, but more of a beware to Vidbid for thinking of using magnetite for his proposed core design.

If you are going to try to use magnetite, BE SURE TO USE LARGE MAGNETS. If you don't, your core will not give rise to much mutual induction between the windings. Now, for clarifying purposes, I am not sure how it will behave as a transformer material if you DO use big enough magnets, but I have personally experimented with magnetite cores and didn't have good results due to the "curing magnets" not being appropriately sized to the core. There is a possibility that magnetite would work, but if you are trying to build a core of any usable size, you will need neodymium magnets that will more than likely frighten you to handle and cost more than you're willing to spend. I believe that Peter Lindemann said that the height of both magnets together has to equal the height of the magnetite domain that you are aligning. Anything else will yield poor results.

Good Luck

Dave

BiTT - Vidbid Modification Mark II



BiTT - Vidbid Modification Mark II

Added two quaternary coils.

Modified BiTT Proposed by Vidbid



The primary is connected to an AC source.

The secondary and tertiary coils should have loads on them.
