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?
Astronomers study the spectrum of light emitted by a star to learn about its characteristics. By analyzing the composition of elements, temperature, and density of a star, astronomers can determine its size, age, brightness, and life cycle stage.
What year did the astronomers find magnatars?
Magnetars were first identified in 1998 when astronomers discovered a new type of neutron star with an extremely strong magnetic field. The discovery was based on the observation of the soft gamma repeater SGR 1900+14, which exhibited bursts of gamma-ray emissions. This finding expanded our understanding of neutron stars and their magnetic properties.
If Astronomers observe a typical star using a telescope and a spectrometer they will be able to determine what?
Astronomers can determine the star's temperature, chemical composition, mass, luminosity, and age by analyzing its spectrum. By studying the absorption and emission lines in the spectrum, astronomers can also infer the star's motion, magnetic fields, and if it has any companions such as planets or other stars.
A rapidly rotating neutron star with an offset magnetic field that appears to blink to a distant observer is called a?
A pulsar

Where is the magnetic field the stroungest?
As far as I know, in a magnetar, which is a special type of neutron star.
Do stars have magnetic fields?
Yes, stars do have magnetic fields. These magnetic fields are generated by the movement of charged particles within the star. The strength and complexity of a star's magnetic field can impact its activity, including its surface features and the ejection of solar flares and coronal mass ejections.
Why would magnetic compass not work in space?
A magnetic compass depends on Earth's magnetic field for orientation. In space, there is no magnetic field to interact with, so a magnetic compass would not be useful for navigation. Other orientation systems, like gyroscopes or star tracking sensors, are used instead in space.
What can astronomers learn by studying star properties?
Very nice one...... 1. The astronomers predict the distance between us and star. 2. The astronomers predict the age of star. 3. By noticing the intencity of light they predict the star is going away or coming near.

The strongest known magnetic field is that of?
A magnetar, a type of neutron star with an extremely powerful magnetic field, has the strongest known magnetic field in the universe, reaching around a billion Tesla at its surface. Magnetars are formed from the remnants of supernova explosions and exhibit intense magnetic field effects such as X-ray emissions and gamma-ray bursts.
How do astronomers use luminosity?
Astronomers use luminosity to measure the total amount of energy a star emits in all directions. By knowing a star's luminosity, astronomers can calculate its distance, size, and temperature. Luminosity helps astronomers understand the life cycle of stars and their evolution.
What can a stars spectrum tell astronomers about a star?
What elements the star is made of.
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.
