Electric Dipole Moments: Sun, Earth, Planets, Minor Planets, Moons

Click For Summary

Discussion Overview

The discussion revolves around the existence and values of Electric Dipole Moments for celestial bodies such as the Sun, Earth, planets, minor planets, and moons. Participants explore the relationship between electric and magnetic dipole moments, the implications of charge imbalances, and the sources of the data presented.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Exploratory

Main Points Raised

  • Some participants inquire about a table of Electric Dipole Moments, similar to one provided for Magnetic Dipole Moments.
  • One participant presents a table of Magnetic Dipole Moments and expresses a desire for a corresponding Electric Dipole Moment table.
  • Concerns are raised about the neutrality of charge imbalances on celestial bodies, with some arguing that they would neutralize over large distances.
  • Others assert that electric and magnetic fields do not neutralize and are distinct phenomena.
  • There is a challenge regarding the source of the presented table, with accusations of it being from a Creationist site, leading to disputes over its scientific validity.
  • Participants discuss the implications of electric fields on planetary bodies, particularly in relation to their atmospheres and core structures.
  • Several participants request references for the claims made, emphasizing the need for credible sources.

Areas of Agreement / Disagreement

Participants express disagreement on the nature of charge neutrality and the validity of the source of the data presented. There is no consensus on the existence of a reliable Electric Dipole Moment table or the implications of the arguments raised.

Contextual Notes

Participants reference various tables and sources, but there is uncertainty regarding their credibility and scientific acceptance. The discussion includes unresolved questions about the relationship between electric and magnetic dipole moments.

Is there a table of Electric Dipole Moments, ##\bar p##, for the Sun, Earth, Planets, Minor Planets and Moons?

Hi there
you have marked your thread with an "I" tag signifying that you are a university undergrad.
So what research have you done so far into this ?
Is there anything specific that you found that you didn't understand and need clarification for ?cheers

The planets, sun,moons,etc act like a dipole for their electromagnetic systems except for the solar wind ejected from the sun or star. The Magnetic Dipole Moment is given from the Table:
No. Body Magnetic Moment at Creation (J/T) Present Magnetic Moment (J/T)
1 Sun 4.65E+29 3.50E+29
2 Mercury 7.50E+22 3.80E+19
3 Venus 1.15E+24 8.00E+17
4 Earth 1.41E+24 7.98E+22
5 Moon 1.73E+22 1.30E+15
6 Mars 1.51E+23 2.10E+18
7 Jupiter 1.79E+27 1.55E+27
8 Saturn 1.34E+26 4.60E+25
9 Uranus 2.05E+25 3.00E+24
10 Neptune 2.42E+25 1.50E+24
11 Pluto 2.60E+24

I am looking for a similar one for the Electric Dipole Moment.
 
Why wouldn't the charge imbalance simply neutralize? And where did this table come from?
 
The Electric is separate from the Magnetic. They do not neutralize. They are similar due to the ##\bar r##. The Magnetic has the ##\bar m## and the Electric has ##\bar p##.
 
Here's what I think - I think you got that table from a Creationist site, and that's why you are spouting non-sequiturs. "They do not neutralize" indeed. That's nonsense.
 
They neutralize as r increases to large levels. With r near to the dipole it definitely has appreciable Electric and Magnetic Fields.
 
If you have a large charge imbalance on a planet-sized object, it neutralizes. Whether you think it does or not. And the fact that you still refuse to say where you got your table from merely reinforces my conclusion that you got it from a creationist site.
 
No disrespect but what about a compass that magnetically faces North. The Electric Field and charge imbalance may be neutralized by the soil and core of the Earth but is it also neutralized in the atmosphere? Jupiter has a large Electric Field because it is mostly a Gas giant.

I could not find the link to the Creationist (Which I am Not) site

It doesn't matter if you are or not. If it is, as you say, a Creationist site, it's unscientific hogwash. And you should have come right out and admitted it rather than string us all along on false pretenses.

that's just a table of numbers

And it doesn't contain the dodgiest numbers, the moments "at Creation".

@berkeman ... this thread still isn't going anywhere useful
I share this opinion.

In case there is a scientific source of your figures, please PM me so.
