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...

Can astronomers learn the magnetic field of a star?
Yes they can do that via the Zeeman effect, by which dark lines in the spectrum of the star are split into multiple lines close together in wavelength by the action of 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. ...

Why is shooting star an inaccurate name for a meteor?
because the shooting star of the shooting star in the galaxy is parr and the field goal of the meteor has to give a striaght parabala and right axis toward the sun. ...
Asked in World Series
Why does the American league have home field advantage in the World Series?
There is an MLB rule that states the League that wins the All-Star game has home field advantage in the World Series. Since the American League won the 2009 All-Star game, 4-3, they get home field advantage for the 2009 World Series. ...
