Toroidal Ferrofluid EPG Video
« on: March 30, 2021, 01:15:09 am »
link to videos  nice graphics !

The first video seems to show a "slug" of  ferrofluid circulating in a hollow toroid
Copper rings encircle the toroid and are spaced equally around the circumference of the toroid

A formula d = r is shown.  It's a little confusing but r is probably the radius of the copper ring
with d representing not diameter of the copper ring but the distance
between the rings.  In terms of EPG design, perhaps this would be a factor in spacing of pumping  and //or  alignment coils.

In the video the speed of the ferrofluid is increasing   relationship to searl  motor  acceleration?

The second video has to do with ferrofluids in general

Hi Jim,

I orderd yesterday some ferrofluid. I want to run some tests before i start to create an epg....
If i can get the fluid magnetised over a certain lenght, i might even run more tests.
