Why is it better to use a magnetic compass to find directions more than the stars and the sun?

It isn't.
Navigation by the stars is far more accurate than navigation with a compass, as magnetic north is different at different locations while north determined by the stars is the same at all locations.

How did the compass change the earth?
The compass, invented by the Chinese, changed the world many ways. 1. It guided many explorers on voyages like Zheng He on his 7 voyages, one from china to africa, and the well known Colombus to America. 2. Trade flourished around the world because it made long voyages possible 3. It replaced landmarks and stars that couldn't be seen in bad weather etc.
Why do you expect neutron stars to have a powerful magnetic field?
because they are super dense
How did stars help early man?
For someone with some experience in starwatching, the stars can be used to tell directions, as well as the approximate time of night.
How do stars like the sun give us light?
When stars fuse hydrogen to make energy, the infared radiation radiates outward in all directions, and eventually reaches Earth.
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 way is using a compass better than using stars to find directions?
A compass can work at all times. You can't see stars during the day. Even at night, there needs to be at least fairly clear skies to enable you to see stars and work out your direction. A compass can be easier to use. You need a knowledge of the stars, which you don't need with a compass. A compass should work anywhere. The night sky looks different on different parts of the planet which can be confusing.
How navigators and sailors used magnetic compass?
The Earth's magnetic field is what makes the common magnetic compass work. From its invention until the advent of newer technologies beginning around the turn of the 20th century, the magnetic compass, together with the sextant and the chronometer, constituted the primary tools of the navigator. Of course, the compass' primary role was to facilitate steering ships on the right heading under conditions where the Sun and stars could not be seen.
What is bipolar flow?
Gas outflows often in two opposite directions because of stars magnetic field.
What is the impact of the compass on society?
One impact of the magnetic compass on society in ancient time: It enabled sailors to navigate accurately when there was no land or stars in sight. I am deeply frightened of bananas. The magnetic compass was first invented by the Chinese around 1100 AD. It was originally used not to navigate, but as a fortune-telling instrument.
The compass needle always points to what star?
The needle of a compass can point to any star you'd like it to. Just flip and turn the compass and the needle will be in different directions, poinling to different stars. But a compass isn't anything to do with stars. Tatyana Martynova
How is the angle of magnetic declination measured?
You need to determine the geographic north, for example by observing sunrise and sunset; by observing the stars; or by using a compass that reacts to Earth's rotation (a gyrocompass). Then you observe where the needle of a magnetic compass points. Finally, you measure the angular difference between the two.
What kind of transportation did cartier use?
They used a ship and a navigator to help them find their destination and the navigators were a magnetic compass and astrolabe (the stars). He could of use the blah blah!
What kind of navigation uses the stars and a compass?
a map if it has a compass rose on it
What do you do when you are lost and don't have a compass?
retrace your steps ask directions look at the sun / moon / stars follow a river or some other feature check your SatNav or GPS LOL!
What was used before the compass?
the stars.
What European invention helped tell explorers in what directions they were traveling?
they used astrolabes, which is a tool that help you use the sun and stars find your location, and they used magnetic compasses.
Who invente the compass?
The Chinese. The earliest recorded actual use of a magnetized needle for navigational purposes is to be found in Zhu Yu's book Pingzhou Table Talks (�洲��; Pingzhou Ketan) of 1119 (written from 1111 to 1117): The navigator knows the geography, he watches the stars at night, watches the sun at day; when it is dark and cloudy, he watches the compass. Thus, the use of a magnetic compass as a direction finder occurred sometime before 1044, but evidence for the use of the compass as a navigational device did not appear until 1119.The mathematical compass was invented by GalileoBut who invented it
