Light that comes from the sun is polarized by these magnetic fields. A meter can determine the different directions of the light and detect interference. This interference is known as a magnetic field.

So astronomer look at the spectrum of a star to find out its magnetic field, using a spectrograph or a spectrometer attached to a large telescope.

If a magnetic field is caused by a charge in motion and if neutrons have no charge where does the magnetic field come from in a neutron star?
The reasons behind the magnetic field of a neutron star are not clear. Neutron stars are the collapsed core of star of 10 to 30 solar masses. One theory is that the magnetic field of a neutron star is because of the conservation of magnetic flux. If a star had a magnetic flux over its surface and the star then collapsed to a much smaller neutron star but the flux was conserved, then the same flux for the neutron star would be spread over a much smaller area making the magnetic field much stronger. But this explanation goes only partway towards explaining the neutron stars' magnetic field.
What part of a star is it that astronomers study in order to learn its characteristics of a star?
Primarily, it's spectrum (it's light seen through a spectrograph).
A rapidly rotating neutron star with an offset magnetic field that appears to blink to a distant observer is called a?
A pulsar
What is the biggest magnet in the solar system?
The Sun's own magnetic field - the star is the largest and most active component of the system.
A pulsar requires that a neutron star 1rotate rapidly 2have a radius of at least 10Km 3have a stron magnetic field 4 rotate on an axis different from the axis of the magnetic field what is tru?
All of the above. See related questions.

Where is the magnetic field the stroungest?
As far as I know, in a magnetar, which is a special type of neutron star.

A pulsar
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.

What are the instruments used by the astronomers to study star?
telescopes
How are neutron stars related to pulsars?
A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field
Is the Aurora Borealis a star?
no the Aurora Borealis is not a star. it is more commonly called the "northern Lights" the effect is when the magnetic field around the earth deflects the radiation from the sun. that is how the "light" effect is caused.
Who studies the star?
firstly, its " Who studies the stars?" the answer is astronomers
How do astronomers use the celestial sphere to plot a star's exact positions?
Astronomers use celestial spheres and mathematical equations to approximate the distances between the star and other celestial objects.
