Kudos for trying to show how the attenuations of your scope probes are set, but what are you measuring with these probes?  Where are these probes connected and to what circuit?

Unfortunately, at the highest resolution of that video available on YT, I cannot clearly see the probes' attenuation switches nor any characters on the scope's screen nor on the signal generator, except for the big LED display of the power supply. 
I even have to assume that the left LED display shows the supply current expressed in Amperes and the right LED display shows the supply voltage expressed in Volts.  Correct?

I think you are showing that at 17mA and 12V power supply you have some high voltage spikes on the red channel, but I cannot see how high these spikes are (the scope's display is not intelligible at 480p resolution)
Are those spikes measured across some resistive load or are they merely unloaded voltage spikes?

Where is the anomaly?  There are many inductive circuits that can produce naked 1kV spikes out of 10mA 12V power supply.

Attention to details clearly isn't your forte.
3 coils (20 turns each, 24G), 2ch driver (IDDX609 + IRF640), no capacitors connected to the coils. Each coil has a negligible resistance.
The third coil (red channel) is the load coil. The resistor in the picture is 5.1 om.

Outside the resonance the circuit exceeds the set current limit of 1.5A. However, @12v 14 mA output is 560V p-p in core resonance.

Like verpies said... what's the anomaly?
When you first mentioned these high voltages, we were discussing the 3V OU Flashlight circuit using the 34063 and the inverter chip, with input of 3 volts. Weren't we? That's the claim that I challenged, and still do. Now you are showing a completely different circuit with a big inductor being pulsed.

So? Did you miss my scopeshot, and the 6-series stack of NE2s as confirmation, showing pulses well over 600 volts, from nothing more than a depleted AAA battery?

I can tell that the probes are set to 10x attenuation. And I don't challenge your measurements, since you aren't using the circuit I thought you were using. And I still say.... so?
