magnetic field of a winding electrified by alternating current

Quando si parla di corrente alternata si parla di un campo magnetico dinamico e ondulatorio fra il voltaggio positivo e quello negativo passando per lo 0.
Con questa rappresentazione si vuole mostrare in che modo è dinamico il campo magnetico in una bobina elettrificata con corrente alternata. Come si può notare, la fuga ipotetica degli elettroni è circolare e parallela rispetto al piano che divide il polo nord dal polo sud.
Questa ipotesi nasce dall'idea che ogni elettrone ha un campo magnetico circolare lungo il filo conduttore.
Il muoversi degli elettroni dal polo positivo al polo negativo del circuito elettrico causa un movimento costante del campo magnetico nella stessa direzione. Un solenoide come la bobina visibile in questa rappresentazione ha un comportamento simile ad un filo conduttore, ma essendo avvolto su se stesso genera un campo magnetico in movimento anch'esso circolare e costante simile alla figura geometrica del toro.
In giallo si può vedere in teoria la disposizione degli elettroni, spinti questa volta dal flusso di corrente, ed il campo magnetico risulta una conseguenza, in nero si possono vedere le lacune elettroniche corrispondenti (questa è comunque una teoria e non è dimostrata - state cauti).


When it comes to talking about an alternating current magnetic field it can to talking about a dynamic wave magnetic field between the positive and negative voltage through 0.
This representation shows how a dynamic wave magnetic field occours in a winding electrified by alternating current. As you can see, the hypothetical run away of the electrons happens circular and parallel to the plane that divides the north pole from the south pole.
This hypothesis comes from the idea that each electron has a circular magnetic field along the wire.
The movement of electrons from positive to negative electric circuit causes a constant movement of the magnetic field in the same direction.
A solenoid coil as seen in this representation has a behavior similar to a wire, but it being wrapped around itself generates a magnetic field and constant circular motion also, forming the geometric shape of the Torus.
In yellow can be seen in theory the electrons provision due to current flow, so the magnetic field became a consequence, in black you can see the electronic gaps corresponding (this is a theory and not proven - be careful).

How can I create a huge magnetic field all around my house? Is that possible?

[pirondinimarco]

@ella5024 A little house, that have 50 meter of perimeter and tall 6 meter, you have to multiply 50 * 6 * 1000 millimeters for have how much long a copper wire must do in meter. The result is 300'000 meters then 300 kilometers of wire. If 16 meters of 1 millimeter have a weight of 110 grams. There need 2'062'500 grams then 2 metric ton of wire. If the costs is 0.10€ to grams of that wire, you have to spend 206'250 euro as 300'000 dollars, for to have 10 cm of magnetic filed all around house. Bye

@ella5024 With alluminium, there is less weight and cost, but perhaps I do not undestand your question very well...

[ella5024]

@pirondinimarco Is there another way to create a magnetic field? I need to be able to destroy and block any plasma, or electrified orbs, from getting near me. I need to push away, or have a away to dispel, plasma.

[pirondinimarco]

@ella5024 There is not, this is the way to create dynamic magnetic field: a winding, but if you want to stop any plasma or electrified orbs, you can try with Faraday Gate, that is an iron grid, you need one much big all around your house, but this can stop lightning also.

Something else I do not know.

[ella5024]

@pirondinimarco I think negative ion generators work, do you think they would neutralize electrified air? I was also thinking of putting metal screens onto fans, and grounding the screens, so it would get sucked on to the screen and be grounded out. I know you must think I'm nuts. The military is trying a lot of crazy stuff on people though, or else someone opened a stargate over me and plasma entities are harassing me. They are, but I don't know how they are doing it.

[ella5024]

@pirondinimarco Is there an easier way? :)
