This video got my attention.
From what I can gather it is a double layered flat Rodin 360 coil.
He is powering it with DC (9 volt battery).
The coil has two wires wrapped around it, so there are two starts and two ends.
The two middle wires are connected as inputs (right and left); and
the outer two are connected as outputs (right and left).
The guy lives in NY and the wires' start/end points need to be facing the SW in order to spin the compass

Edit: I wanted to add an image in case this turns out to be something interesting and the video disappears.
Hi duff.
The first thing he needs to do to be believable, is to achieve the same effect with a real compass. Pulsing in to that Rodin coil could be messing with the electronics in the phone, so I personally don't have much confidence in that at the moment.

Here's what he says:
QuoteI am basically passing a DC current (9 volts) through the coil. The coil has two wires wrapped around it, so there are two starts and two ends. The two middle wires are connected as inputs (right and left); and the outer two are connected as outputs (right and left).
It is a very low voltage that I'm using for this experiment. I am also using a straight DC current; not a pulsed signal, so my Neo ball will not spin the same way.
It works in any position but doesn't spin in every position.
From where I am in NY, the wires' start/end points need to be facing the SW. No other position allows the spin.
This is not clear, and not enough info, so I agree with POYNT.
Don't know what he means by input and output. Understand that 9 VDC is connected to input wires. What is connected to output wires? are they shorted together?
However, if something is spinning too fast for a regular compass, it would seem similar to Hendershot's early work. Also related to TPU operation.
My work in this area showed that a mechanical compass will stop spinning if the pulsing is too fast. Perhaps he needs to ramp the DC voltage up slowly so that the mechanical compass has a chance to keep up. In any case the mechanical compass will quit when the rotating field gets too fast and cannot keep up.
Definitely need more info....nevertheless interesting.
The video is interesting.
I would like to believe the coil could rotate something with DC but I'm forced to consider the difference between a real compass and one made using software and sensors.
A real one will do nothing if placed in the center of a 'net zero magnetic field'. Some call that a cancelled field.
The virtual compass may do almost anything. It depends upon the hardware and software.
The display of the compass seeming to work at a given rotational angle indicates to me that his Rodin coil has uneven leakage.
