What is a device that has a magnetized needle that spin freely?
A compass has a magnetized needle that can spin freely.
What is a device that has a magnetized needle that can spin freely?
A compass has a magnetized needle that can spin freely.
What has a needle that is magnetized to the north pole?
a compass
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.
Where does the needle on a compass normally point and why?
The needle on a compass normally points towards the Earth's magnetic north pole because it is magnetized and aligns itself with the Earth's magnetic field.
What magnetized steel needle that aligns with the magnetic of the earth is a?
A compass needle is a magnetized steel needle that aligns with the Earth's magnetic field. Its use allows for determining directions such as north, south, east, and west.
What a compass needle be made from?
Answer:A compass needle can be made from any ferrous metal that can be magnetized.
What is used to make compass needles because it is magnetic?
Compass needles are typically made from magnetized materials such as iron or steel. These materials are able to become magnetized and align with the Earth's magnetic field, allowing the compass needle to point north.
Does a compass contain a magnet?
Yes, a compass typically contains a magnetized needle that aligns itself with the Earth's magnetic field to point towards magnetic north.
Why do you float magnetised needle to a cork floating in water?
When a magnetized needle is placed on a cork floating in water, it aligns itself with the Earth's magnetic field. This allows the needle to point north-south, making it a simple compass. The buoyant force from the cork keeps the needle afloat without sinking.
A device that has a magnetized needle that spins freely?
The device you are describing sounds like a compass. The magnetized needle aligns with the magnetic field of the Earth, allowing users to determine their direction relative to the north.
What do the poles of a magnetized needle on a compass align themselves with?
The poles of a magnetized needle on a compass align themselves with the Earth's magnetic field, pointing towards the magnetic north and south poles. This alignment helps the needle to indicate the direction of north.
