When the needle of a compass points in a certain direction that means that the poles of earth have alined it so the point is pointing to the north pole (because earth is a magnet) so In conclusion the poles of earth are being attracted to the opposite pole of the needle because opposites attract and the needles in compasses are designed to point the "pointy" part at the north pole. (pretty smart for an 11year old).
To be a little more technical, all magnets have a magnetic field going out from its North Pole and entering back in at its South Pole. When in another magnetic field, the fields will exert a force to try to align the field lines. If near a ferromagnetic material, such as iron, the field lines are distorted and exert a force between the magnet and the metal to realign the fields. Since the compass needle has a small mass, and easily spins, it is usually the object which will move.

What is the thing that helps the needle move freely in a compass called?
From an Engineering standpoint, it is called a BEARING. In a cheap compass it is a simple PINPOINT in the Base, and a CUP on the bottom of the Needle.
Why does a needle of a compass move when you put a bar of metal close to it?
The compass needle is a magnet and as you have probably tried, a magnet will 'stick' to an Iron bar. Thus as you move the compass near the Iron, its magnetic field lines are bent by the Iron and become locally stronger than the field lines of the planet, deflecting the needle away from north.
Which describes how a compass works?
. The south magnetic pole of the compass points to Earth's north magnetic pole.
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 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

When a flows in a wire a compass needle near the wire will move?
The wire will move due to magnetic forces got from the compass needle since its a good conductor of electricity.

Why does the needle on a compass move when placed in the coil of wire?
It moves because it wants to have compass babies with raccoons and so it won't get high it move and that is it giving birth

Compass needle move when a current switched on?
this is because of magnetic field formed when the current flows through it. this is called electromagnetism. if we move the compass needle away from current carrying conductor or wire it returns to its position (north south position)
What is the purpose of the Lensatic Compass?
A lensatic compass is a compass with a magnifying glass on the sight which makes it easier to view the needle. These types of compasses are frequently used in the military.

What is the magnet in a compass?
The compass needle.
What is the circuit's total resistance?
You take the wire(s) that are in the circuit and place it on on a compass. Hold the compass still and the needle in the compass will move. However far that the needle is turned will detrmine how much resistance is in the circuit. (You know you have done this correctly if the needle in the compass spins counter clockwise.) Hope this helps you out :)
