Magnetic compasses become ineffective in submarines because surrounding steel hulls and electrical equipment distort Earth’s magnetic field, causing inaccurate readings, especially when submerged deep underwater for reliable underwater navigation systems.

Why does a compass needle change direction when it is near a magnetic field?
Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.Because of the magnetic force. The compass needle is also magnetic.
Will a compass always work?
No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

What direction does the magnetic needle of a compass point to?
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
What happens when a compass is brought into a magnetic field?
When a compass is brought into a magnetic field, the needle of the compass will align itself with the magnetic field lines. This is because the needle is a magnet itself and is influenced by the magnetic field of the Earth or any external magnetic field it is brought into.
Why is a magnetic compass not useful for navigating a submarine?
A magnetic compass is not useful for navigating a submarine primarily because submarines operate underwater, where the Earth's magnetic field can be distorted by the surrounding water and the metal structure of the vessel itself. Additionally, the compass relies on detecting magnetic north, which becomes unreliable due to the varying magnetic influences underwater. Instead, submarines typically use inertial navigation systems, GPS (when surfaced), and other advanced navigation technologies to determine their position and course accurately.
Why would a magnetic compass not work in space?
A magnetic compass relies on Earth's magnetic field to indicate direction, which is absent in the vastness of space. In space, there are no magnetic field lines to align the compass needle, rendering it ineffective. Additionally, the microgravity environment can affect the compass's operation, further complicating its use beyond Earth's atmosphere.
Why is a magnetic compass useless inside a submarine?
They're not - all submarines use both standard and electronic compasses for navigation.
What happens when you stroke a needle 20 times with a magnet?
it becomes magnetic :)
Is gyrosyn compass a combination of magnetic compass and artificial horizon?
No,a Gyrosyn compass is a combination of a Magnetic compass and Direct reading compass.

What instrument is used for determining direction?
A compass. The North magnetic pole is in the direction of the N on the compass. Therefore, the North magnetic pole is in fact a magnetic field south pole since it *attracts* the north magnetic field pole of the compass magnet.
How does a compass needle respond when a compass is placed in a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
How does a compass needle respond when a compass is placed with a magnetic field?
If a magnetic compass needle is placed in a magnetic Field , its needle deflects and points in the north and south directions
What direction does the magnetic needle of a compass point to?
The magnetic needle of a compass points towards the Earth's magnetic North Pole.
Which invention is more important the astrolabe or the magnetic compass why?
In my opinion I think the magnetic compass is more important because It made worldwide travel easier and encouraged more exploration.
