How do they measure gauss from distant stars like pulsars, or maybe it
is just an estimation, if they can what kind of instrument is used?

This is why you should read the literature. Zeeman splitting &
spectroscopy is a reliable way to determine ambient fields.

What is actually measured with a gaussmeter?

Magnetic flux.

Hello Eric!

Thank you for your short but brief answer.
How strong is the magnetic flux field outside earth electro magnetic
field is the flux itself harmful?

Field is not flux.
Flux is the integrated amount of field that passes through a given
surface area.
Magnetic flux can only do something useful when it changes.

But a stationary barmagnet have both field and flux, where the flux is
the strength at a certain distance over a certain area?

But if i replace the cone on a speaker with a bar magnet and let it
oscillate in 1200 hz, is that an oscillating flux or a magnetic field
transmitter?

Does such phenomenon exist in nature magnetic fields that oscillate,
what about neutron stars?

What could i use to measure pickup the oscillating flux would it be
sufficient with an iron ring and copperthread linning?

Would that be a primitive gausmeter?

I would like to try to build an magnetic transmitter and receiver that
work over a couple of meters. "For audio to start with" could you give
me some advice or isn't it feasible?





The other night i watched the start of Moobase Alpha and i found it
utterly fascinating.

Do the spacecrafts carry gaussmeter or other equipment to measure the
local flux field, i read that a pulsar have an enormous flux field how
do it propagate through space. I guess the inverse square law is not
applicable to magnetic fields. How do you calculate the flux field
strength from a pulsar "gauss?" outside earths shielding magnetic
field.

Magnetic fields propagate through space the same way electric fields
do in that they are simply there. A dipole field falls off as 1/r^3,
which is far faster than gravity.

Is the spaceshuttles and spacestations within earths electro magnetic
field?

Earth's magnetic field - depending how you measure - extends for many
Earth radii in all directions. Some more than others, though.

Besides the radiation, how do they shield the spacecrafts from fluxes
in the electro magnetic surrounding "space?", or is it not necessary?

You can shield it but why? The ambient field is weak, and does not
change rapidly enough to harm anything. Except spacecraft during
events that rapidly compress the field, but that's complicated.

What happen to a body if there is strong fluctuations in the magnetic
fields would it cause sickness, at how many gauss will the body and
cells get damaged?

Strong fluctuations will induce current. A strong static field will
'encourage' anything with unpaired electrons to align, and fields that
are strong enough will start to interact with the fantastically weak
diamagnetic properties of water.

At some point, I have no idea where, the field will disrupt the
biochemistry by totally borking out the ion channels in your body.

I am interested but know very little about magnetic fields, magnetic
radiation and magnetic flux.

If we somehow could align strongly repelling magnets in a straight
plast tube along a 300 000 km line in space.

We then push the first one how long time would it take before our
gaussmeter in the other end noticed a change in the flux?
