How could you magnetise a needle to make your own compass?
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
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.
How did Albert Einstein get interested in his field?
One day when he was little, he got sick and his father gave him a magnetic compass to play with. He was fascinated by whatever way he turned the compass the needle still pointed the same way.
How does a compass needle respond when a compass is Place with 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 needle is placed within a magnetic field?
A compass needle, as well as everything else on Earth, is ALWAYS within a magnetic field. If the compass needle is free to turn, it will align itself with the magnetic field, and point along the north/south axis of the field. If another magnetic field source appears near the compass ... such as a current-carrying electrical conductor, or a toy magnet in somebody's pocket ... whose field strength is comparable to the Earth's, then the compass will deflect, and realign itself along the north/south axis of the SUM of the fields.
Which way does a compass needle usually point?
The needle, or "pointer", of a compass will always point North. See: http://en.wikipedia.org/wiki/Compass
The needle on a compass is always pointing to what pole?
The north pole.
What pole does the needle on a compass always point to?
the north pole
What is the purpose for a needle on a compass?
to point the right direction ***correction by cw - the needle always points north.

Compass with east and west reversed why?
It's a direct reading compass, meaning that whatever direction you are pointed in, the needle will show your heading. Meaning that if you are facing north, the needle points north. Rotate 90 deg. to your left, and the needle now rotates clockwise 90 deg...to the letter labeled W.
Where will a compass point if you face south?
If you point the north side of the compass away from you the compass will point south. Because the needle always points north (magnetism).

What is the magnet in a compass?
The compass needle.
What does the painted point of a compass always always point 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.
What major changes set the stage for European exploration?
the major discovery that was made on 1271 to 1295 was the compass that was made to find direction's compass was an instrument used to find direction's also includes a needle that always pointed north
What can be used for a compass?
a freely suspended magnetic needle as it will always point to the north - south direction
