I want to give you a little more insight!
In a big "Generator", I want to ask you to put yourself between the Rotor and Stator Coils as the Rotor Spins.
In-between the Poles:
As the Rotor Spins, we see some effects that are extremely simple to understand!
As the Stator Coils Voltage is Zero, and the Rotor Approaches, the Stator Coils Voltage Increases, and if the Coil is loaded, the Stator Coil will have a Current Flow, calculated by Ohms Law!
The Magnetic Fields will Oppose each other, and the Shaft will see a Negative Torque that is a function of the Current, MMF, as a Drag on the Shaft, making the Shaft harder to turn. Very basic 101 Electromagnetic Induction!
This is only part of the Cycle, please go and study this further if you need.
This Opposition of Magnetic Fields is the very same process seen here:
The swinging Magnet slows and stops due to the M.M.F, it is Magnetic Drag or Breaking as mentioned.
Each Coil, one on the Stator and one on the Rotor, has a part Cycle when the Fields are 180 Degrees Out of Phase, equal and Opposite. This process "Generates" Electrical Energy!
Partnered Output Coils do the very same thing:
The Input Coil Simulates the Rotor Motion, as in a Transformer, we use an Input Coil to give the Transformer a Time Rate of Change of the Magnetic Field, this produces a Voltage on the Output Coil, and a Current can flow according to Ohms Law.
A Transformer is Not Above Unity simply because it is Symmetrical, Input = Output - Losses!
Partnered Output Coils use the exact same Working Principles as a "Generator" or a Transformer, except we employ Asymmetry and our Input Coil sees very little Negative Force or Torque! One of our Partnered Output Coils Assists your Input Coil, giving your Input Coil an assistive Force, which reduces a good portion of its Current, and thus reduces the Input by a very large factor. In other words, its internal Impedance goes way up!
This is so Simple! Any child could make this work!
