No force operates in a vacuum... for there to be an equal and opposite reaction, the essence of force... there must be a background field in which these features live... can push against, vibrate within etc. If there is no background field then there is no containment and energy dissipates in all directions endlessly even prior to its own manifestation.. such as a weightless arm attached to nothing trying to throw a tomato at a glorious politician. Nothing will happen..
..there is nothing against which to create an equal and opposite reaction... the tomato will simply hang in space.
IF that is the case then the opposite to an electrically induced magnetic field will be induced,,necessarily in its polar opposite in all respects, a conductive mass. the mass must then dissipate that energy ... in the form of heat or of static lines of magnetic force...or in some other fashion...rotation for instance if the electrically induced field can be arranged to impinge on the iron mass in such a way as to induce torque.,,but for any of that to manifest there must be a background field in which these operate, and can provide leverage on each other.
And indeed we do see this reciprocity all through physics.. for instance the recently proven time and space warp around planets... something is being warped...and that something is the background field that our manifestation is written within...
We are currently attempting to understand these issues from a false notion that these forces are created and exist in a perfect vacuum...
that has limited our discovery. we have failed to define 'vacuum' and conclude that one can have a perfect vacuum if there are no tiny rocks in the space...'its a vacuum'... well yes. Its a vacuum relative to rocks. but it is about as far from a perfect vacuum of all-that-is as can be imagined.
To parse this it helps to ask yourself how does any wave motion travel? Waves in the ocean for instance...sound waves etc...these travel as compressions and decompressions in air and pressure gradients in water as it rises and falls in wave motion..
So what of electro magnetic *waves... this wave motion travels in a true vacuum? No ... there is a background field. We have simply not detected... even as are off in search of the missing mass in the universe...sort of like a fish searching for wet... the fish would not even have the notion of wet.. wet is an issue only where there is dry...and there is no dry in the ocean...its all wet you see.
Forces of any type do not exist in a perfect vacuum...they cannot. and they do not.. an examination of the Hubbell photos will demonstrate very familiar patterns as seen with smoke within a field of gas...yet there is no particular field of gas in the outer space.. there is a field of some other construction... particles act entirely differently in an air vacuum...
with electro magnetic energy we are looking at nothing more than finer 'particles' operating in an even finer background field.
To see the manifestation of this background field look at picture of the horse head nebula... that dust cloud formation, millions of light years across...is not totally diffuse... it has hard edges.. that is its particles interface with a more or less equally dense, but alien to its own structure background field.
When we define that field... physics will have taken another giant step forward,
this is the life work of thousands of scientists..with a few unable to fathom such a thing in opposition..
We have simply not detected it yet...why? Because our instruments operate and are dependent on the background field to exist imo and operate.. the self does not detect the self.. differentiation is the essence of detection. From inside the background field there is no detection possible of the background field.
..except by extrapolation from an exterior view point.. that is a point of view beyond the limits of the material construct...and noticing the differences in impedance through this field...for instance thought is seen to traverse this field with no discernable resistance or time lag across thousands of miles... I had that discussion ever so briefly with Dr Wolfgang Stroebel (from east Germany during the time of the cold war no less when he was contracted to develop his neutrino mass experiment at LLNRL in the US... described later by Col Bearden who headed that and much other leading edge research.in his book published a few years after his retirement and vetted appropriately.)
So do we understand the actual mechanics of how an electric motor works? I suggest that one understand how a jet engine works in a background field of air... then look with that in mind, extrapolating for the background field that supports electro mechanical drives..and the milky way galaxy on which a distant branch our solar system lives as an invisible spec to all but the nearest of our neighbors.
This massive entitiy demonstrates very obvious drag through a pervasive background field. the mass of that field is calculable and is currently being calculated... and shown at great suprize very recently as the force by which the universe is *accelerating its expansion.
For that acceleration to be taking place... this field must be repulsive to its condensates or impurities... celestial bodies. The mechanics of that repulsion define the nature of and structure of the field.
It is observably rigid to intent, observably tansparent to manifestations .... and unfathomable to its offspring.
A human being operates on this interface. by pushing the limits on manifestation, as seen in life and death situations and some kinds of motor racing that are on the absolute edge... the being defaults from the manifestation to pure intent.
