What else can I help you with?
A compass works because it's magnetic needle?
Will point to the magnetic North Pole.
Why do you use iron in compass needles?
Because the iron used in the needle (A lodestone I think it is sometimes called) is naturally attracted to the magnetic north of the planet, so in theory the compass will always tell you which direction north is.
What is the name of the line with which a compass aligns?
A needle
When and where was the compass invented?
The first compass was invented in China by a man who noticed a certain point always faced one direction. (I think)
What was the ancient Chinese compass used for?
used for direction
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.
When a current flows from east to west what direction will a compass point to?
A compass needle aligns with the Earth's magnetic field, which typically points north. In this scenario, with a current flowing from east to west, the compass needle will still point north. The direction of current flow does not affect the orientation of the compass needle.
What is the purpose for a needle on a compass?
to point the right direction ***correction by cw - the needle always points north.
What direction does the needle of a magnetic compass point?
The needle of a magnetic compass points towards the Earth's magnetic north pole. This allows users to determine their direction relative to the magnetic poles.
Determine the direction in which a compass needle will point when held above a wire with positive charges moving west?
The compass needle will point towards the wire, perpendicular to the current flow. Since the positive charges are moving west, the magnetic field generated by their movement will induce a force on the compass needle causing it to point towards the wire.
If you made another compass with the same materials would the needle point be in the same direction?
the needle points in the direction the magnetic fields wish. The gravity pulls the compass nearer and nearer the magnetic fields.
What can be used for a compass?
a freely suspended magnetic needle as it will always point to the north - south direction
Why does the compass point north in the southern hemisphere?
The direction of magnetic flux or lines of force is from north polarity to south polarity, and a compass needle will always align with that direction, wherever it is used. Since the magnetic polarity of the location we call Magnetic North is a south, a compass needle will point in that direction.
Why does a compass needle change direction?
A compass needle changes direction because it aligns itself with the magnetic field of the Earth. The Earth's magnetic field is generated by the movement of molten iron in its outer core. This causes the needle to point towards magnetic north.
How does a bar magnet interact with a compass?
A bar magnet interacts with a compass by aligning the compass needle along the magnetic field lines of the magnet. This causes the compass needle to point towards the North Pole of the magnet, allowing the compass to indicate the direction of the magnetic field.
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
What direction does a compass needle point if a current carrying wire is wrapped around it?
The compass needle aligns itself parallel to the direction of the lines of magnetic force where it happens to be. It does not 'point to a particular pole' for that is beyond the sensibility of a simple bar of metal. I repeat, it aligns itself parallel to the lines of magnetic force ...
