Magnitite Cores 2

[alannowod]

Hello Sir, How did your Fe3O4 cores work for you. I am reading that when the material is wet, it needs to be aligned by putting a magnet on each end to make the material line up in parallel... do you know anything about this ? I hope to know how your trifler coil and magnetite core worked !!!!

What if u had a a way to compress the air around the mold...to maybe help with compressing the mix

Fe3O4 can be found on eBay. Very Cool. Thanks.

Found a local source in Sydney for black iron oxide, $9.50AU for 500g. Going to try and make a large'ish core for a coupling transformer (TIG welder HF start) - Thanks again for the vid!

Sulphur is NOT attracted to magnets (write that down in your copy books.)

Good video, very informative

Where did you get the iron oxide ?

Thanks for sharing

You can buy it on ebay

Cool video! I was actually thinking of something like this a few days ago for a Fluorescent tube driver

Should work good for that project, you may consider making a toroid or other closed loop flux path for that for higher inductance. Look on ebay for Fe3O4 its pretty cheap.
