With the right lighting, you could make it flow up. Or atleast it could look that way.

POV is my next thing to play with, after finishing the build.
Thank you

Just to note, the energy stored in the coil is proportional to the Volt Seconds which is simply volts times the time in seconds. That means to dissipate a given energy W first the stored energy can be looked at as:
W=v*s*K
with K a constant, and to dissipate that energy we have to dissipate W units, so we have the same:
W=v*s*K
Now if we quantify the energy going in:
W1=v1*t1*K
and going out:
W2=v2*t2*K
and so with unsigned voltages we must have close to:
W2=W1
to dissipate nearly all the energy.
This simply means:
v2*t2*K=v1*t1*K
reducing, we get:
v2*t2=v1*t1
and if we solve for the dissipation time we get:
t2=t1*v1/v2
and here it is plain to see that as we increase v2 the time t2 reduces and that's the goal.
t1 is automatically limited because of the fixed voltage v1, but obviously if v1 is lowered t2 reduces that way too.
So the rule is minimum v1, maximum v2. The practical limit on v2 is closely related to the drain source voltage rating of the transistor so the choice of transistor is also a key factor.

Too much for a Hobbyist to understand ;D

Hi again,
Ok no problem, just look at the last couple lines:
The rule is minimum v1 (applied voltage) and maximum v2 (discharge voltage)
and of course a transistor that can handle v2 without being destroyed.
