That's pretty high. Is that measurement taken right up against the mechanism?
Yes, touching the hub.

Any data from varying distances?
I do, but it's probably not very useful to you. I had it hooked up to a Servodisc motor that produces about 1.4 uT.

Since there's no electricity involved, I wonder if it's a non factor for ES? Or is it creating electricity by the resistance?
That's how they work, unfortunately. (en.wikipedia.org/wiki/Eddy_current_brake)

Their only saving grace is that the electric current in the disc is DC and stays in the same place. If the disc were perfectly symmetrical and rotated at a constant speed, the field near it would be like a bunch of permanent magnets. Unfortunately the disc in the Magturbo has a lot of vent holes that shift the current around as they go by the permanent magnets, which rattle at the same time.

What was your experience?
I didn't like using either trainer, but I had them in an area with wiring problems.
