In which direction will each compass point?
A compass points north because all magnets have two poles , a north pole and a south pole, and the north pole of one magnet is attracted to the south pole of another magnet. (You may have seen this demonstrated by a pair of simple bar magnets or refrigerator magnets pushed end to end.)
How does a compass needle respond when a compass is placed within a magnetic field?
The magnetic field is a zone where the force is active along imaginary lines. From the south magnetic pole to the north magnetic pole, this force has an effect on all magnetized objects, such as the needle of a compass. Under the effect of Earth's magnetic field, the needle always points toward the north magnetic pole.
Does a compass always point north?
A magnetic compass does not point to the geographic north pole. A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic north pole is actually the south magnetic pole. When it comes to magnets, opposites attract.
Which way does a compass point in the Southern Hemisphere?
Simple compasses for use in the southern hemisphere have the north-pointing end of the needle weighted to prevent this. In fact, manufacturers of compasses customize them for five separate geographic zones. Magnetic compasses used by explorers of the American West were weighted for use in North America.
What happens to a compass at the south pole?
What that means is, if you were to visit the South Pole bearing a compass with a free-floating needle that could move in three dimensions, the "south" end of that compass needle would point straight down once you reach the magnetic South Pole, Jordan told Live Science.
What happens to a compass at the north pole?
If your compass is at the geomagnetic north pole, which is somewhere in northern Canada, it wants to point straight down. Since it is constrained to be level it will wander aimlessly around.
In which direction will a magnetic compass point if it is placed at the magnetic north?
Earth's magnetic north pole is near Earth's geographic south. That's why the north pole of a compass points toward north because that's where Earth's south magnetic pole is located and they attract.
What happens to a compass at the magnetic north pole?
If your compass is at the geomagnetic north pole, which is somewhere in northern Canada, it wants to point straight down. Since it is constrained to be level it will wander aimlessly around.
What happens to a compass at the South Pole?
What that means is, if you were to visit the South Pole bearing a compass with a free-floating needle that could move in three dimensions, the "south" end of that compass needle would point straight down once you reach the magnetic South Pole, Jordan told Live Science.
Who invented compass?
China Historians think China may have been the first civilization to develop a magnetic compass that could be used for navigation. Chinese scientists may have developed navigational compasses as early as the 11th or 12th century. Western Europeans soon followed at the end of the 12th century.
How do compasses point north?
Earth's south magnetic pole is near Earth's geographic north. Earth's magnetic north pole is near Earth's geographic south. That's why the north pole of a compass points toward north because that's where Earth's south magnetic pole is located and they attract.
What happens to a compass in the North Pole?
more in Science Q&A Now, on to your question…if you were standing exactly on top of the magnetic north pole, your compass would point nowhere in particular since the place it is used to pointing to is at your feet!
What happens to a compass in the South Pole?
What that means is, if you were to visit the South Pole bearing a compass with a free-floating needle that could move in three dimensions, the "south" end of that compass needle would point straight down once you reach the magnetic South Pole, Jordan told Live Science.
When a magnetic compass is placed on a ground to find the direction its needle will stay along?
The earth has only vertical component of its magnetic field at the magnetic poles. Since compass needle is only free to rotate in horizontal plane where H=0, hence the compass needle may stay in any direction.
What happens to a compass in the south pole?
What that means is, if you were to visit the South Pole bearing a compass with a free-floating needle that could move in three dimensions, the "south" end of that compass needle would point straight down once you reach the magnetic South Pole, Jordan told Live Science.

Who invented paper?
Cai LunElmer L. GadenJohn Dickinson Paper/Inventors About 2,000 years ago, inventors in China took communication to the next level, crafting cloth sheets to record their drawings and writings. And paper, as we know it today, was born! Paper was first made in Lei-Yang, China by Ts'ai Lun, a Chinese court official.
Who invented the Internet?
Computer scientists Vinton Cerf and Bob Kahn are credited with inventing the Internet communication protocols we use today and the system referred to as the Internet.
Why does my compass point south?
Reverse polarity is where the magnetism in the compass needle becomes permanently reversed so the red end of the needle points south instead of north. This is different to the magnetic needle being temporarily deviated a little when near a metal object or weak magnet and correcting itself as soon as it is moved away.
Which way would a compass point if you were at the north magnetic pole of the earth?
Earth's magnetic north pole is near Earth's geographic south. That's why the north pole of a compass points toward north because that's where Earth's south magnetic pole is located and they attract.
Where does compass point at North Pole?
Now, on to your question…if you were standing exactly on top of the magnetic north pole, your compass would point nowhere in particular since the place it is used to pointing to is at your feet!
What is China paper?
Paper is a thin material made by pressing of moist fibers and drying them into flexible sheets. It is most commonly made from cellulose pulp derived from wood, rags or grasses. It is used for various uses but usually for printing, writing and wrapping.
Who invented school?
Horace Mann invented school and what is today the United States' modern school system. Horace was born in 1796 in Massachusetts and became the Secretary of Education in Massachusettes where he championed an organized and set curriculum of core knowledge for each student.
Who invented phones?
Alexander Graham BellAntonio MeucciJohann Philipp ReisAmos DolbearCharles A. CheeverJohn Peirce Telephone/Inventors It is not easy to determine who the inventor was. Both Alexander Graham Bell and Elisha Gray submitted independent patent applications concerning telephones to the patent office in Washington on February 14, 1876.
What happens to a compass at the equator?
It's only on the equator that a typical compass will provide the most accurate reading about which direction is north and which direction is south, Jordan said. That's because at the equator, all of the planet's magnetic field lines are horizontal and parallel to Earth's surface, he explained.
What happens to a compass when you stand on the north pole?

What is silk China?
Silk is a fabric first produced in Neolithic China from the filaments of the cocoon of the silk worm. It became a staple source of income for small farmers and, as weaving techniques improved, the reputation of Chinese silk spread so that it became highly desired across the empires of the ancient world.
Who invented the silk?
According to Chinese legend, Empress His Ling Shi was first person to discover silk as weavable fibre in the 27th century BC.
Who invented exams?
Henry Fischel Henry Fischel, an American Philanthropist and businessman, is credited as the person who invented exams. He created the Imperial Exam in 19th century China for the assessment of candidates to become government officials.
Who made homework?
Roberto Nevilis Going back in time, we see that homework was invented by Roberto Nevilis, an Italian pedagog. The idea behind homework was simple. As a teacher, Nevilis felt that his teachings lost essence when they left the class.
