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.

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.
What is the thing that helps the needle move freely in a compass called?
The thing that helps the needle move freely in a compass is called a pivot or bearing. It is usually a low-friction point that allows the needle to align with the Earth's magnetic field and point north.
Why does a needle on a compass move?
A needle on a compass is a magnet, and it aligns itself with the Earth's magnetic field. This allows the needle to point towards the magnetic North Pole. The movement of the needle is a result of the interaction between the Earth's magnetic field and the magnetic properties of the needle.
What must be done first to an ordinary sewing needle to make it a compass needle?
To make an ordinary sewing needle into a compass needle, it must first be demagnetized by heating it to a high temperature and then allowing it to cool in a specific orientation. This aligns the needle's magnetic domains and makes it a more effective compass needle.
Why does an compass needle move when it is brought near an electromagnet?
A compass needle is a tiny magnet that aligns with the magnetic field around it. When brought near an electromagnet, the magnetic field produced by the electromagnet affects the compass needle, causing it to align with the new magnetic field created by the electromagnet.
What feature of the Earth makes a compass needle point north?
What features of the earth makes a compass needle point north
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 can't visible light move a compass needle?
Visible light can't move a compass needle because light consists of electromagnetic waves, while a compass needle is affected by the Earth's magnetic field. The magnetic field from visible light is not strong enough to influence the orientation of a compass needle.

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

What is the name of a compass needle?
The needle in a compass is typically called a magnetic needle or magnetic pointer.
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)
