How does a navigator work?
A compass contains a needle which shows the holder north and south when the needle turns. A compass contains a lightweight magnet and fricitionless bearing to connect with the earths magnetic field otherwise the needle cannot be turned.
How does a magnetized needle work?
The magnetic field of earth exerts a torque on the needle, pulling one end or pole of the needle toward the Earth's North magnetic pole, and the other toward the South magnetic. The needle is mounted on a low-friction pivot point, in better magnetized needle a jewel bearing, so it can turn easily. When the magnetized needle is held level, the needle turns until, after a few seconds to allow oscillations to die out, one end points toward the North magnetic pole.
The device that turns a needle in a galvanometer is called an electromagnet?
The device that turns a needle in a galvanometer is called a coil or a solenoid. It generates a magnetic field when current passes through it, causing the needle to deflect in response to the current being measured.
What is the device that turns a needle in a galvanometer?
The device that turns a needle in a galvanometer is called a coil. The coil generates a magnetic field when current flows through it, which interacts with the magnetic field produced by the permanent magnet in the galvanometer to cause the needle to deflect.
How does a compass work using the Earth's magnetic field?
a compass has a magnetic point which points to the north pole. well yes but....a compass has a magnetic needle inside it which attracts it self to the earths magnetic field. it may not actually point to the norht pole but actually to the earths magnetic north pole
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
When a plant turns toward the sunlightthat is called?
Tropism
Is a Hawthorne bush needle poisonous?
No. Only if the wound turns septic, but that is not the hawthorns fault.
Is concession the wobbling of the earths axis as it turns in space?
bugel says yes
How does erosion help in bringing fossils to the earths surface?
erosion helps bring fossils to earths surface by when a animal dies it turns into a fossil
What causes two distinct pressure zones between equator and the poles?
The Earth's rotation turns the polar high pressure systems westward as they move from the poles (westerlies), and the subtropical high pressure systems eastward as they move toward the equator (tropical easterlies).
Are U-turns legal in North Carolina?
Yes, U-turns are legal in North Carolina unless there is a sign specifically prohibiting them.
