Bifilar pancake coil overunity experiment

[ayeaye]

No there is no luck to get overunity. I played with the circuit below rather randomly, using ngspice, maybe you get some idea what such thing does. These two coils are coupled, like on the same core. Netlist was the following.

* Spice netlister for gnetlist
K1 L1 L2 0.999
L2 n1 0 200u
L1 n0 n1 200u
R1 n2 n0 100
C1 0 n1 50n
V1 n2 0 dc 0 pulse 0 5 0 5n 5n 3u 100u
.END

The image below is  plot n0-0 , after  tran 10n 30u . I printed  (n0-0) * (n2-n0) . The output of that is some tsv, but my python script worked with it pretty well. The output was the following.

Input 1501.44444818
Output 1474.84738893

This is the Python script that i used, i redirected the output of the ngspice print command to input.txt. I did it in the ngspice shell,  print (n2-n0) * (n0 - 0) > input.txt . I don't know how this can be done with LTspice, but there sure has to be something similar. LTspice can use netlists made for ngspice, these are both spice, though LTspice may use somewhat different models.

def nextf(sl, separator):
  endp = sl[0].find(separator)
  if (endp == -1): endp = len(sl[0])
  tok = sl[0][: endp]
  sl[0] = sl[0][endp + 1 : ]
  if (tok == ""): return 0.0
  return float(tok)

line = [""]
ei = eo = 0.0
f = open("input.txt")
while (True):
  line[0] = f.readline()
  if (len(line[0]) == 0): break
  line[0] = line[0].strip()
  if (len(line[0]) == 0): continue
  if (not line[0][0].isdigit()): continue
  nextf(line, "\t")
  nextf(line, "\t")
  p = nextf(line, "\t")
  if (p >= 0): ei += p
  if (p < 0): eo += p
f.close()
print("Input " + str(ei))
print("Output " + str(-eo))

This above couldn't be done with spreadsheet. The output of the print command is tsv, but one cannot read it into a spreadsheet, as it has things written at the beginning and in between the pages, also lines like  --------------------------------------- .

Python eats all things well though. One may think, nextf() is the next float value. Its arguments are line in the list form, and separator, which is "," for csv, and in this case tab. It goes to the next iteration when the first character is not digit, which omits all lines that are not tsv. The first value may be negative, so "-" should be allowed also, which couldn't be allowed in this case.

Then, all positive values were added as input, and all negative values were added as output.

In fact what i think there may be, maybe that is, i don't say that there is. That the current induced, is not determined by the speed of change of the magnetic field, but is greater, when a part of the current goes somewhere else, moving only a short distance, like to a capacitor.

The simulation thus cannot show it, as it assumes that the current is always proportional to the speed of change of the magnetic field (Faraday's law).

The simulation seems to show that this is how simulation works, as by that like in the beginning, the capacitor decreases the increase of the voltage, thus decreasing the change of the magnetic field. A part of the energy that otherwise goes to increasing the magnetic field, then went to charging the capacitor. And then it seems to show that after the pulse ends, the energy stored in the capacitor goes back to the coil, to delay the current reaching zero, thus increasing the generated energy. But this comes from the energy by which the magnetic field was increased less. Thus simulation might not show the possible overunity even if it were there.

We cannot eliminate the Lenz law, because induction is the Lenz law. We may only increase it and redirect it. Like in this case, it supposed to be redirected to charging the capacitance. Certain work has to be done to increase the magnetic field, which means working against the charges in the atoms of the core, which means resistance to the current, it cannot be otherwise. The only question is whether the effect of induction can create the opposite current more than that.

About this picture below, why i showed that. I'm not of any religion, don't misunderstand. It shows fire wheels, and why i showed these.

Because atoms are the fire wheels that move the universe.

There is a saying that "comparison is not reason".
Metaphors and comparisons are processes of religious writing designed to convince without thinking. These are the best traps for not understanding science questions.
