What must be done first to an ordinary sewing needle to make it a compass needle?
To make an ordinary sewing needle into a compass needle, it must first be demagnetized by heating it to a high temperature and then allowing it to cool in a specific orientation. This aligns the needle's magnetic domains and makes it a more effective compass needle.
Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
In What year was the first magnetic compass used?
The first magnetic compass was used in ancient China around 206 BC during the Han dynasty. It was initially used for divination and later adapted for navigation.
What was Einstein's first invention?
Einstein's first invention was a device called the magnetic compass, which he created when he was just five years old. He was captivated by the way the needle always pointed in the same direction, sparking his curiosity about the natural world.
How much did a grid compass 1100 weigh?
The Grid Compass 1100 weighed around 5 pounds, making it one of the first portable computers.

Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
What was the first compass made out of?
The first compasses were made out of lodestone, a naturally occurring magnetic rock. The lodestone was typically floated on a piece of wood or straw in water to allow it to align with the Earth's magnetic field, indicating the cardinal directions.
How would you tell someone how to use a compass?
To use a compass, first hold it flat in your hand and make sure the needle is pointing north. Then, rotate yourself and the compass together until the red end of the needle aligns with the "N" on the dial. Your direction of travel is now indicated by the direction of the compass arrow. Remember to account for declination if necessary.
Who was the first to notice that when electrons flow through a wire a nearby compass needle moved?
Oersted first noticed this around 1820.
How would a southern hemisphere compass differ from a northern hemisphere compass?
The Southern Hemisphere compass will naturally align it self with the South Poleanswer 2 A compass designed to work in the southern hemisphere will have the needle/card balanced differently, for in the S hemisphere the S pole will cause the compass to dip slightly - and opposite to the northern hemisphere.The compass manufacturers divide the Earth into five zones for balance. Some folk need a compass that is insensitive to this effect, (e.g. Army) and for this they choose to have the needle a smaller part of the weight balanced on the pivot, and have a liquid filled compass.Regarding the first sentence above, the compass needle actually aligns itself with the lines of magnetic force at your location - which will still result in a N - S alignment.
What did the first compass look like?
The first compass was a simple magnetic needle floating in water, with markings indicating the cardinal directions. It lacked a housing and was more primitive compared to modern compasses. Early compasses were used for navigation by aligning the needle with Earth's magnetic field to determine direction.
What is the The north magnetic pole of a compass needle is attracted to the magnetic pole of the earth.?
The needle on a compass points to the North Magnetic Pole. CommentA compass points to Magnetic North, not to the north magnetic pole. They are two different things -the first is location, the second is magnetic polarity.
What is the difference between surveyors compass and prismatic compass?
PRISMATIC COMPASSThe graduated ring remains stationary as it is attached to magnetic needle. While the compass needle and the eye sight vane can be rotatedThe graduations are made in such a way that 00 or 3600 is at the south, 1800 at north, 900 at south and 2700 at eastSighting of the object and the taking of reading is done simultaneouslyPrismatic compass can be used without a tripodSURVEYORS COMPASSThe graduated ring being attached to the compass moves with sights. But needle remains stationary when box is rotatedThe graduations are made as 00 at north & south 900 at east and west. The east and west positions are interchanged in order to read the bearing in quadrantal bearing systemSighting the object is done first. Then the reading is to be taken with naked eye by looking above the needle pointSurveyor's compass cannot be used without a tripod
What was the compass made out of?
The compass was traditionally made with a magnetized needle floating in a liquid-filled housing to orient itself toward the Earth's magnetic field. Modern compasses can also incorporate electronic components to provide more precise readings.
Why does a compost attract to a north magnetic and repel by the south?
OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
Where fiber was produced first?
The Swiss chemist, Georges Audemars invented the first crude artificial silk around 1855, by dipping a needle into liquid mulberry bark pulp and gummy rubber to make threads.
