Easiest way to inquire about this subject is, why doesn't a capacitor become magnetized if the domains in the dialectic are aligned the same way as a magnet?
Thank you for your expertise!
It is appreciated!

 

Dielectric, by the way.

Would you elucidate your comment: "the domains in the dialectic are aligned the same way as a magnet"?

Dielectric materials typically used in capacitors have a magnetic permeability of ~1, with air being diamagnetic, and PTFE being weakly so, but such materials can't be magnetized in any case.

See the list, below.

Material	Relative Permeability \mu_r	Notes
Air	~1.0000004	Diamagnetic
PTFE (Teflon)	~1	Weakly diamagnetic
Polypropylene	~1
Ceramic (Class I, e.g., C0G/NP0)	~1
Barium titanate (Class II)	~1	High \varepsilon_r, still non-magnetic
Glass	~1

 

Well I guess that domain alignment is not the only factor. I think I read that free electrons made a difference too. Domain alignment is the most stated cause of magetism but actually is not if you count dialectics. So what makes a Dialectic different? it has domains.

 

My own logic was that if a substance could have it' domains arranged to from front to back that it would be magnetic.

 

Posts #2 and #3 are both correct, but consider that tose "domains" in a capacitor are ELECTRIC FIELD domanins, not megnetic field domains. AND , know for certain that in afew materials that capacitor charge DOES REMAIN for quite a while.

 

Only way for nascence of magnetic field is electrical charges moving.
Static charges generate electrical field.

The only domains that might appear in a dielectric are ferroelectric domains. These are not magnetic, they have no magnetic properties, and they require a ferroelectric material such as the Barium Titanate used in some SMD capacitors.

Ferromagnetic domains have nothing to do with ferroelectric domains.

Ferromagnetic domain: uniform spontaneous magnetization (in a ferromagnetic material)
Ferroelectric domain: uniform spontaneous electrical polarization (in a ferroelectric material)

The only similarity between the two is structural. You should also be aware that a dielectric material in a capacitor does not have to he ferroelectric and so most capacitor have no domains—electric or magnetic—as part of their attributes.

This is a very important point. Electrons produce magnetic fields only in motion, in a charged capacitor they are at rest. The magnetic field associated with the charging/discharging of a capacitor is identical to the magnetic field in a wire when current flows. The presence of a dielectric has no effect on it, it is related to conductors.
