Sailors were and are able to use the Earth's magnetic field to navigate the seas because of the consistency of its orientation. The simple device known as a compass, which is used to indicate the direction of the Earth's magnetic field, contributes to navigational cues by giving an orientation of the ship through the act of comparison to the direction of the Earth's magnetic field, thus yielding useful information about the direction in which the ship sails. Unlike celestial bodies which can also be exploited to provide navigational information, the compass usually operates day or night and regardless of whether the sky is overcast. There are of course nuances in the operation of the compass, such as variation and deviation - allowances for slight local changes in geomagnetic force and differences between true north and magnetic north depending on global position (such as latitude).

How is earths magnetic field used by people and animals?
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.
The way in the Earths core spin is believed to be the source of its?
magnetic field.
At the earths magnetic north pole it is pointless trying to use a compass to find your way?
That's correct. At the magnetic North Pole, the Earth's magnetic field lines are nearly vertical, causing compass needles to point straight downwards. This makes it difficult to navigate using a compass, as it will not give accurate readings.
What are two primary differences between an electromagnets magnetic field and earths magnetic field?
First one is artificial where as the latter is natural We could increase or decrease the strength of magnetic field but we cannot vary earth's Intense field could be produced but earth's field is feeble in comparison with artificial
What instrument show north west east south in ship?
A ship's compass, also referred to as a magnetic compass, is the instrument that shows the cardinal directions: north, east, south, and west. The compass needle aligns with the Earth's magnetic field, allowing sailors to navigate and steer the ship in the desired direction.
How is the earths magnetic field used for navigation?
Compasses use the magnetic field to navigate always pointing North.
How is earths magnetic field used by people and animals?
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.
What was the name of the stone used by early sailors as a primitive compass?
The stone used by early sailors as a primitive compass was called a lodestone. Lodestones are naturally magnetized rocks that were used to help sailors navigate by aligning with the Earth's magnetic field.
Is earths core a source of earths magnetic field?
Yes.
How are the Earths magnetic field made?
It is made by the movement of the earths core and magma field
Earth's magnetic field results from the spinning of the?
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Why do scientists believe that the inner core is the source of earths magnetic field?
because it has the hydro electric power to control the earths magnetic field
What is earths magnetic field called?
It is Earths' "Magnetosphere".
Where does the earth's magnetic field get its power from?
earths magnetic field is generated by the circulation of liquid metal.
What is the magnetic field called?
It is Earths' "Magnetosphere".
What is another word for earths magnetic field?
= An effect of the magnetic field is "Van Allen radiation belt" =
What is earths field that reverses from time to time?
The Earth's Magnetic field.
