a compass
By observing a compass needle.
When you sail with a magnetized needle, it will point towards the magnetic north pole. This is because the needle aligns itself with the Earth's magnetic field, which is used for navigation purposes.
It is still a needle, but could be referred to as a compass needle.
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.
There is a magnetic field surrounding the Earth. The positive pole of this magnetic field (called the north magnetic pole) is near the North Pole. A compass has a freely rotating needle that is magnetized such that one end of the needle points toward the north magnetic pole.
towards the magnetic North Pole.
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.
A compass has a magnetized needle that can spin freely.
A compass works by aligning itself with Earth's magnetic field. The needle inside the compass is magnetized and points towards the magnetic north pole. By following the direction the needle points, you can determine which way is north.
The painted end of the compass needle is magnetized. That magnetism is drawn toward the earth's magnetic field, which is to the north.AnswerA compass needle is a tiny magnet, with a north pole and a south pole. These poles are named after the direction in which they point, so the 'painted end' (north) of a compass needle points north because the needle aligns itself with the earth's magnetic field. Magnetic North is the name given to a location, close to True North, whose magnetic polarity is south -which is whyit attracts the north pole of the compass needle.
A Compass! A common science experiment involves rubbing a magnet down a needle (only one way!) and putting it in a "boat" in a bowl of water to demonstrate a simple compass! The Earth has a core of iron. This makes a magnetic field, with north pointing (almost*) at the north pole, and south at the south pole. *Magnetic north is not the north pole. Actually, compasses point to a place in northern Canada
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
