I was considering using 22 AWG soft steel wire to make transformer cores.
Just wind a coil out of it to the size core I want and then wind the copper wire around it.
How would this do? What works better, using thiner or thicker wire?

The game here, is to avoid eddy currents induced in the core, by the coil. Eddy currents waste power and produce unwanted heat. If using wire, best bet would be a very tightly bound bundle of thinly insulated iron wires, and not a coil. This is the reason most transformer cores are sheet laminations or ferrites (bound iron dust) The excerpt I found (below) is a more technical description of what is going on.

Assume that a changing magnetic flux is passing through a certain square cross sectional area of the transformer core. Look at a loop of current enclosing that flux. The power dissipated in that particular loop is proportional to the square of the area enclosed by that loop (A) divided by the length of the path (L). If you divide that square into two rectangles by laminating the core, the area enclosed in the loop will be cut in half while the length will be reduced to 3/4 of the original length. The result will be two loops of current with a total power dissipation of 2X(.5A)^2/.75L. That makes the sum of the power dissipated in the two smaller loops two thirds of the power dissipated in the original loop. More laminations reduce the dissipation even more.

please forgive my ignorance:Isn't the input energy still higher than the output energy? 
for example: 300% increase of 5 watt = 15watt is still lower than 43% of 50watt=21watt
Where am I missing the point?

CONVENTIONAL GENERATOR HIGH CURRENT COIL TEST #1
(Generator High Current Coil output with High Voltage Coil open circuit)

I/P = 237 W
O/P = 0.6 W

HIGH VOLTAGE COIL TEST #2
(Generator High Current output with High Voltage Coil short circuit)

I/P = 166 W
O/P = 2.41 W

I/P POWER % DECREASE = 237 - 166/237 x 100 = 30% DECREASE
O/P POWER INCREASE = 0.6 - 2.41/0.6 x 100 = 302% INCREASE

THE ONLY DIFFERENCE BETWEEN TEST#1 AND TEST #2 IS THE APPLICATION OF THE HIGH VOLTAGE COILS - WHICH ACCELERATE THE GENERATOR ROTOR AND CAUSE THE PRIME MOVER POWER TO DECREASE AND THE HIGH CURRENT COILS' OUTPUT TO INCREASE.

TEST #1 CONFORMS TO LENZ'S LAW and TEST#2 DOES NOT.

THE PRIME MOVER INPUT POWER IS A REFLECTION OF THE MOTOR'S EFFICIENCY AND THE KEY POINT OF INTEREST IS THE MOTOR'S REACTION TO LOADING.  - IF THE HIGH VOLTAGE COILS WERE ALSO CONFORMING TO LENZ'S LAW THEY WOULD ALSO CAUSE DECELERATION.

THE HIGH VOLTAGE COILS CAUSE ACCELERATION BECAUSE THEIR HIGHER IMPEDANCE CAUSES THEM TO FUNCTION AS CAPACITORS RATHER THAN INDUCTORS AND THEY STORE ENERGY IN THEIR ELECTROSTATIC FIELD BETWEEN THE WIRES RATHER THAN THE ELECTROMAGNETIC FIELD AROUND THE WIRES - AS PER LENZ'S LAW.

BE PATIENT WITH YOURSELF ALAN AND KEEP ASKING QUESTIONS - YOU MAY BE SUFFERING FROM A RARE FORM OF POLARBREEZEDIMENTIA - THERE IS A CURE BUT WE MAY HAVE TO REMOVE 1/2 YOUR BRAIN IF IT PERSISTS.

p.s. THANKS FOR THE QUESTION MY MATH WAS WRONG...

As I have already had both hemispheres of my brain removed (due to a gardening accident), I now find the best cure for POLARBREEZEDIMENTIA is just eating a Klondike bar.

But that would leave me with 1/4 of my brain, I like it this way. Fortunately I am patient, like a hungry spider 

It starts to make sense.
So it accelerates because there are no contra forces that normally slows the rotor down. These are absorbed by the HV coil as capacitance, so no magnetic interference.
Something like that, still foggy, but understanding will come. Need to recheck electromagnetic theory.
I think this thing could be modelled mathematically (you done that I see), maybe it could even be made solid stade, but these are premature assumptions of mine, need more understanding.
