Negative Inductance and measure of Magnetic force.

Quote from Vladimir Utkin:

"BI-FILAR PANCAKE COIL –The voltage between adjacent turns in an ordinary coil is very low, and so their ability to generate additional energy is not good. Consequently, you need to raise the voltage between adjacent turns in an inductor. Method: divide the inductor into separate parts, and position the turns of the first part in between the turns of the second part, and then connect end of the first coil to the beginning of the second coil. When you do that, the voltage between adjacent turns will be the same as the voltage between the ends of the whole coil !!! Next step – rearrange the position of the magnetic and electric fields in the way needed for applying amplifying energy (as described above). The method for doing this is – the flat pancake coil where the magnetic and electric fields are arranged in exactly the way needed for amplifying energy.


Now, it is clear why Tesla always said that his bi-filar pancake coil was an energy-amplifying coil !!!

REMARK: for the best charging of the natural self-capacitance of the coil, you have to use electric pulses which are as short as possible, because the displacement current as shown in Maxwell's equation, depends to a major degree on the speed of the change in the magnetic field".

Quote from Utkin:

"Definitions of Physics: Any conductor has both inductance and capacitance, that is, the ability to accumulate charge on it's surface. A charge on the surface of a conductor creates an electric field (electrostatic field). The potential (voltage) at any point of the electric field is a scalar quantity!!! (That is, it is a scalar electric field ...)".


If the electric charge of the conductor varies with time, then the electrostatic field will also vary with time, resulting in the appearance of the magnetic field component:"

@smoKy2,

The NIC is an Op Amp circuit. The Op Amp is an integrated circuit. The last two examples are negative capacitance followed by negative inductance. The difference is the reversal of the inductor and capacitor position in the feedback loop. I don't believe the negative inductance application the author's talking about is the "Inverse Henry" that we measure with the inductance meter, but a value that applies to the function of the Op Amp.

The pertinent question is; Let's say your correct about a magnetic field in the alligator clips, "Is the magnetic field in the clips a value measured by the inductance meter in the negative range"?

The INIC (not VNIC) is the tool used for proper circuit analysis
of a negative inductance.
Eliminates measurement errors.


And having magnetized alligator clips can CAUSE measurement errors
because of the way the meter measures inductance.


The way you were playing with that choke, it is likely that you magnetized them.

@smOky2,

The choke reads normal rated inductance immediately after the magnets are removed.

Here's another simple test
Apply a voltage across the inductor


Using the measured ohmic resistance, calculate the current.


Next, using the inductance formula, calculate the current
by inserting the (negative) value you measured for inductance.


Next, measure the actual current.


Here's a circuit that will help you understand what negative inductance
is.
