When we close in a soft iron or ferrite a magnetic flux composed for a constant magnetic field such as the generated from a permanent magnet and an altern magnetic field we can see an energy and power amplification without violation of the conservation of energy because a magnetic field is energy and the increment of energy becomes from the field

The energy U stored in a magnetic field of B induction in a volume V is

U = 1/(2*mu0) * B^2 * V

Where mu0 is the magnetic permitivity of the vacuum

The power we can get of the field is

P = dU/dt

So with a permanent magnet U(t) is constant and P becomes zero and we don't can get power from a magnet, but if we enclose the magnet in cores of iron or ferrite , the magnetic circuits will have a constant component of field due to the permanent magnet and a altern component if we add a coil for pulse the total field, the field in any magnetic circuit will be

B(t) = Bo + Bf * Sin(w*t)

Bo the permanent magnetic component , Bf de peak altern component of the coil, w the angular frequency of the altern source

The voltage induction in any other coil for get the power for the Faraday Law will be proportional to dB/dt and so the permanent magnet component Bo becomes unnecessary, redundant and inductions works like if there is not a permanent magnet in the core, but if we evaluate the output power P(t) before calculated we find

P(t) = 1/(mu0) * (Bo + Bf * Sin(w*t) ) * w * Bf * V * Cos(w*t)

and now yes, the power output was in dependence of Bo and a power gain in relation if there is not a magnet in the system, that is say Bo = 0 , and we can compute the COP of the system for the ratio between P(t) with magnet to P(t) without magnet for peak or rms values, and we can see many great values start from 3 to the clasic MEG to N + 1, where N is the number of magnetic circuits in the system when there is not gaps in the device, when there is Gaps the COP can rise up to 40, 100,200,....and more

a good design of the system must be consistent from the COP and calculations of the magnetic circuits, not saturation and other details , that is say in the COP calculation there is values for Bo, Bf, w, where theres is bad values where COP < 1 and the design is bad

This is like build a transistor is not too easy and not hard but all manufacturer must know very well what is building , for the beginners I don't recomend ferrites, is best common 60 Hz or 50 Hz iron has a magnetization B-H curve more wide, in other way all is random

This basical equations show for this MEG devices of any type there is not exotic resources for claim a COP>1, esoteric causes, scalar waves,etc, only classic and traditional electromagnetic theory
