A PLACE FOR DEBATE

Voltage == e-field == tiny magnetic field arround wire...

Whats to debate?

A non-moving electric charge would not be considered to have a magnetic moment.  The term "non-moving" is a matter perspective, ,as evrything can be considered moving when compared to something else.  The whole universe is moving around.

A moving electron has been shown to have an intrinsic magnetic moment.  If you have moving electrons  and hence a current (i.e. charge carriers) they generate a magnetic field.

From Hyperphysics:

But how does the electron obtain a magnetic moment if it has zero angular momentum and therefore produces no "current loop" to produce a magnetic moment? In 1925, Samuel A. Goudsmit and George E. Uhlenbeck postulated that the electron had an intrinsic angular momentum, independent of its orbital characteristics. In classical terms, a ball of charge could have a magnetic moment if it were spinning such that the charge at the edges produced an effective current loop. This kind of reasoning led to the use of "electron spin" to describe the intrinsic angular momentum.

Add this to some of the things that Edward Leedskalnin wrote, and a current loop (or closed magnetic loop) gets a little interesting.

No wire, a static charge in the atmosphere with no current. No potential, difference causing electron flow. Is there a magnetic componet?

[Grumpy]

I was refering to a static charge.

So, no. Why would it need to have a magnetic moment?

The electric field (potential) can exist without it's magnetic field partner.  (Ref. a paper by F. Mende)

[Dingus Mungus]

"does a standing static charge have a magnetic componet?"
If it carries a charge it carries voltage.

I'm not sure we all agree on what voltage means...

As I understand it voltage is potential difference between two points which causes current to flow. Static field voltage works the same way and doesn't really require a wire, just a secondary point to measure the electrical potential difference or voltage. If you meassure a electrical potential difference that means current can flow and when it does a magnetic field will be present.

If I'm mistaken please explain.
