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.
The compass revolutionized navigation by allowing sailors to determine their direction at sea, enabling exploration, trade, and ultimately the globalization of cultures and economies. It played a crucial role in shaping world history by making long-distance travel more efficient and accurate.
The needle is magnetic, so it follows the magnetic North pole.Do an experiment.Take a magnet, put it in some water.It will turn and point north.Put it in at any angel, it doesn't mater it will always point north.But make sure its a light magnet.The northern lights are caused by the magnetic north pole to.
a long time ago the compass was made of wood now a compass is made of steel

WILL The exact location where a compass points will ever change?
No, the exact location where a compass points (magnetic north) does not change. However, the magnetic poles themselves can shift over time due to changes in the Earth's magnetic field.
What feature of the Earth makes a compass needle point north?
What features of the earth makes a compass needle point north
What is the function of the earth induction compass?
An Earth induction compass uses the Earth's magnetic field to determine direction. It employs a coil that interacts with the Earth's magnetic field to provide an accurate indication of north.
Is compass attracted to magnet?
Yes, a compass is attracted to a magnet because the needle inside the compass is magnetized and aligns itself with the Earth's magnetic field, which is created by the interaction of the Earth's core and crust. This allows the compass to point towards the magnetic North Pole.
What is the moveable bar in a compass called?
The movable bar in a compass is called the compass needle. It is typically a thin magnetized bar that aligns with the Earth's magnetic field to indicate direction.
Why does a compass change direction when a metal is near?
When a metal object is brought near a compass, it can disrupt the Earth's magnetic field around the compass. This disruption causes the compass needle to align itself with the new magnetic field created by the metal object, resulting in a change in direction.
Can a magnetic compass reading change?
Yes, a magnetic compass reading can change due to fluctuations in the Earth's magnetic field, interference from nearby magnetic objects, or errors in calibration. It is important to regularly check and correct the compass reading for accurate navigation.
WILL The exact location where a compass points will ever change?
No, the exact location where a compass points (magnetic north) does not change. However, the magnetic poles themselves can shift over time due to changes in the Earth's magnetic field.
How compass changes direction?
A compass needle aligns itself with the Earth's magnetic field, pointing towards the magnetic North Pole. When the compass is moved or rotated, the needle remains aligned with the magnetic field, causing it to change direction accordingly.
Why does a compass needle change direction?
A compass needle changes direction because it aligns itself with the magnetic field of the Earth. The Earth's magnetic field is generated by the movement of molten iron in its outer core. This causes the needle to point towards magnetic north.
What feature of the Earth makes a compass needle point north?
What features of the earth makes a compass needle point north
How does the earth act like a compass?
magnetic pull which is what the compass works off of.
Is a compass needle a transformer?
No, a compass needle is not a transformer. A compass needle is a simple magnetic instrument that aligns itself with the Earth's magnetic field to show the direction of North. Transformers, on the other hand, are devices used to change the voltage and current levels in electrical circuits.
When was the compass first created?
since the earth is generaly a compass in itself, it was created by god.
What is the function of the earth induction compass?
An Earth induction compass uses the Earth's magnetic field to determine direction. It employs a coil that interacts with the Earth's magnetic field to provide an accurate indication of north.
How compass navigate the earth?
A compass works by aligning with the Earth's magnetic field. The needle inside the compass is magnetized and points toward the Earth's magnetic north pole. By using this reference point, travelers can determine their direction relative to the north.
Where does a compass point during winter?
Compass points always towards Earth's magnetic north.
