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?
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.
Is the spaceshuttles and spacestations within earths electro magnetic
field?
Besides the radiation, how do they shield the spacecrafts from fluxes
in the electro magnetic surrounding "space?", or is it not necessary?
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?
I am interested but know very little about magnetic fields, magnetic
radiation and magnetic flux.
Terrestrial surface field is below 0.4 gauss and dropping.
Refrigerator magnets are about 100 gauss. MRI tunnels are abut 10,000
gauss. Pulsars are around a billion gauss. The vacuum is estimated to
break down around 1-10 trillion gauss.
Electrons spiral around magnetic lines of force. Strong magnetic
fields therefore elongate atoms. You don't want to be in fields
beyond around 50 teslas lest your biochemistry go for a Burton.
How strong is the suns magnetic field using gauss, what formula should
i use to calculate how it diminish with distance?
Later you are talking about teslas, how does this unit relate to the
measured gauss.
Screw your lazy ignorant ass into a chair and google it. Ignorance is
educable, stupidity is forever.

;) maybe i will i saw a formula on wikipedia to calculate so i
probably could.
Meanwhile i give you something to ponder over, not that i think you
know or can calculate the answer...
If we somehow could align strong 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?
