as i understand coils when a current flows in a conductor it creates a magnetic filed like rotating in a direction.
in a transformer there are two coils. when you pass current in the first it creates magnetic filed. when you withdraw current from the second coil because of flow of the current in the second coil it creates a magnetic filed that like rotates in the opposing direction to the magnetic filed of the first coil. the filed of the second coil that opposing destroys the magnetic filed of the first.
and then there is nothing.
my idea is to rotate the magnetic filed that going in the core by 180 degree at the other side.
so when i will take current from the second coil the magnetic filed that will be created
will be in the same direction of the magnetic filed of the first coil.
i propose to create a core in form of infinity sign (like 8 rotated on the side)
this core may be used with a transformer.
may be it will be possible to create accelerating magnetic fields and a no back-emf transformer
its possibly only "the same way"
pese
do you say that it is the same way?
is there a different way to retore a magnetic filed by 180 degrees?
also attached a different idea.
i do not sure about it.
hi shimondoodkin,
have a look at this link:

Does anyone know of anyone that has tried to make a motor by switching B field flux ?

Hi Gary, if you could obtain pvc coated soft iron wire, that would serve well for some experiment. You could form a longer bundle of core from several iron wires run in parallel, the thickness of the bundle is of your choice or maybe coil bobbin/form. Soft iron usualy has a permeability of at least some hundred or so. PVC coating is a must to prevent eddy currents between the parallel turns just like in case of laminations.
China is a big supplier of cheap wires but if you google for 'pvc coated iron wire', you may find locally in hardware stores at gardening/fence stuffs. A Chinese source is like this: http://www.alibaba.com/product-gs/204434420/Fine_Quality_PVC_Coated_Wire.html or http://www.alibaba.com/product-gs/204301967/PVC_coated_iron_wire.html to see what I mean. It is good you have got a small magnet with you when buying around in hardware stores ;)
This seems to be the cheapest but still a good way for exploring either your or the link's ideas, I have not done it yet.
rgds, Gyula

Thanks Gyula
I have a few pounds of iron wire for tying rebar with .......I was thinking that painting it would be a pretty good insulation . ....... maybe not as good as PVC but hopefully good enough to play with a little while
I will have to think about the best way to make a motor ....... I really like the idea of being able to shut off the b field flow by oversaturating the wire .
Control over the field coils with ZERO contact and ZERO electronics

wow thanks for link it is amazing
i think in fig 8 there is no flow because thereÃ, is only a 90 degrees force redirection and no force atÃ, 0 degres
this also a good feature to insert in to a magnetic filed an inductor being undetected
and then to introduce it to the system with large torque. to create no load generator.

fig 13 may interesting to TPU dreamers
it says that when you put a magnet on it it makes a core to become non-magnetically-conductive because of saturation and the transformer does not work then, while it is saturated. and that the opening of this switch reduces the inductance of the iron ring, and causes the primary to draw an enormous current. also BREAKING THE CIRUICT PRODUCES A "SHORT CIRCUIT" EFFECT!
maybe such magnetic switch can be made by DC wire aroundÃ, the core.
and (not sure:)
i saw in a patent that there are holes in the center of a core so maybe it switches off just a half of a core(in the width)
to produce waves. - in a toroid with 4 holes symmetrical
it does in a sequence:
two upper parallel on
two upper parallel off
other two lower parallel on
other two lower parallel off
and the same sequence goes again. maybe it produces some fluctuations in the filed.
