Producing current from sun magnetism?

[jumpjack]

Several years ago Tethered experiment demonstrated that current can be produced by a long wire moving in Earh orbit, due to Earth magnetism.
Being Earth inside Sun magnetosphere, wouldn't it be possibile to accomplish same task in a long wire properly positioned on Earth surface? Possibly at poles, where I as far as I understand solar magnetism is less shielded by Earth's one.

You sure it is current and not voltage?

If you have a conductor moving in an uniform magnetic field, there would be a potential across its ends, however no current can exist.

as far as I unerstand, current flow was allowed by discharging the excess voltage in the space using some kind of an "electron gun" at an edge of the wire, thus "closing" the circuit.

Found study on tethered satellites (quite long...):

Found a shorter explanation:

when a conductor moves through a
magnetic field, charged particles in the conductor experience an
electrodynamic force perpendicular to both the direction of mo-
tion and the magnetic field. So if a tether is moving from west to
east through Earth’s northward-pointing magnetic field, electrons
will be induced to flow down the tether [see illustration on pre-
ceding page].
The tether exchanges electrons with the ionosphere, a re-
gion of the atmosphere in which high-energy solar radiation
strips electrons from atoms, creating a jumble of electrons and
ions, called a plasma. The tether collects free electrons at one
end (the anode, or positively charged electron attractor) and
ejects them at the opposite end (the cathode, or negatively
charged electron emitter). The electrically conductive iono-
sphere serves to complete the circuit, and the result is a steady
current that can be tapped to use for onboard power. As a prac-
tical matter, in LEO a 20-kilometer tether with a suitable an-
ode design could produce up to 40 kilowatts of power, suffi-
cient to run manned research facilities.

But I think on Earth surface I'd miss electrons source...
I have a moving magnetic field, a "gun" to eject electrons... but I have no ionosphere to get electrons from!

You could get them from a salty solutions, or just closing the loop with more wire. Trying to answer OP's question, is the solar magnetism even strong enough at Earth? If you put a compass at a distance of 1 AU from the Sun, but somewhat far from Earth so it's magnetic field won't influence it, would the compass still align with the Sun's field?
