it attracts to magnetic north, which is 13 degrees away from real north
By nature they must.
But there are now electronic ones.
A magnetic compass has a small bar magnet that is free to rotate and aligns itself with the Earth's magnetic field.
It depends on the type of compass. Some do, and some don't.
It depends on the type of compass. The common ones, with a freely-moving needle, do indeed have a magnet.
Magnetic north
In a regular magnetic compass, the needle is a magnet. One end is the south pole and the other end is the north pole. Magnets are affected by other magnets. If a magnet is placed near a magnetic compass, the north pole of the compass's needle is attracted by the south pole of the magnet, and the south pole of the compass's needle is attracted by the north pole of the magnet.
No. compasses use a complex spinner.
They used compasses to navigate on the sea and on land.
No it doesnt affect it. In fact there are some compasses that utilize water as a surface. If the water caused a problem with the magnetic field of the earth, it would be useless for creating a compass; it would never be correct.
All electric motors use magnetic force. So do electrical sound amplification systems. Magnetic levitation of high-speed trains is another example.
a compass is a permanent magnet
yes
A. Compasses typically use a permanent magnet.
Compasses
They use the fact that the earth acts as a giant magnet so that compasses point towards the north pole.
because of the earth's magnetic core
A compass has both a south pole and a north pole :)
In a sense, the Earth is a natural magnet, with north and south poles effecting compasses. Naturally magnetized piece of the mineral magnetite, commonly known as lodestone, is an example of a natural magnet..
Thepermanent and atemporary magnet.
Useful - even before humans discovered compasses and "electric" motors, the Earth's magnetic field protected our atmosphere.
The plural possessive for compasses is compasses'.
most of the time. some times they willy not work if you drop it but some times if they are made out of a natural magnet they will last forever.
