Why is a permanent magnet not a source of energy?

[The Observer]

Micro,


Try making a speaker without the use of Ferros ( the magnet and the core that is inside the coil )
and you will find the actual energy it takes to make the sound.


    1. Replace the magnet with an air coil.
    2. Take the core out of the coil that drives the diaphragm.

By adding ferromagnetic substances to the mix ( the magnet and the core inside of the coil ),
you increase the intensity of the sound for the same signal.

The higher the Magnetic Permeability of the ferromagnetic substances added... the louder the sound is going to be.
The energy comes from moving unpaired electrons in the Ferromagnetic Substances that act as a permanently energized coil.

See diagram below to understand this.

The so called strength of a magnet is just the term describing how much magnetic potential energy it actually has. If you look into a physics literature, you will see that any material for magnet is described with the energy density parameter. The neodymium one has the greatest values. Even if this potential magnetic energy isn't repeatedly used in device like overunity magnet generators, it surely exist and without this energy none of speaker or magnet motor would work. The problem is rather how it is possible to magnetize once a magnet (giving it some energy in this process) and not discharging it with typical use for years. And this is connected with the crystal structure. But now we have neodymium magnets with their great energy density and most of machines with overunity are possible to create in practice. The old pulverized magnets hasn't this amount of potential energy. If you'll read about SEG, there is clearly suggested that the used permanent magnets need to be very strong - hard to obtain in '1950s. I see that some of You are believing in theories that the magnetism as interaction is something more than spin of electron and it is connected with perturbations of space. I think it's a good way for future understanding and maybe such thinking will enclose another good unification theory of interactions.

Maybe in a speaker all the energy comes from amplifier as electricity, only the magnet flux allows the coil with the membrane to change this energy into movement with greater efficiency than only the coil. I know it is possible without the magnet inside, because once I connect a wire resistor into amplifier output and it begans to play (weird, but really happens .

More field lines means a stronger field which means more dragging effect thus more conversion between electricity comming from the amp into kinetic motion, which in turn moves the voice coil and  the diaphragm.
The amount of field lines cutting the voicecoil has a direct relationship to the produced kinetic movement and this has got nothing to do with the magnet supplying energy the energy comes from the amplifier.

Is there anything which can limit the amount of field lines connected to the voicecoil?

Good to know something new microcontroller, thx. First look at any magnet motor really gives you feeling the energy is drawn from magnets. For example in Kapanadze where there's nothing unusual except for the grounding it is easier to see that the energy is really from the unknown source. I think that simply a century or two must remain to describe better radiant energy, zero point energy and other theoritically existing things which is probably just the unknown space, even Albert. E. was claiming that space is something more than <<empty space>>. We now only see particles like electrons, bozons etc. and who knows what is in the depth (Feynmann stayed there is much 'in the depth'). Overunity devices works and I think that governments if they want or not need to create a institute to work with the topic not only in secret maying in vision the Star Wars.

I was today playing with my old magnets trying to discover something new - a pulse motor and I need to point I love to play with magnets even if nothing special is happening Magnets rules!
