answ2. A needle may easily be magnetized by gently stroking it in one direction. This can be converted into a compass which you may carefully float on the surface of water, where it will align itself with the lines of magnetic force at your location.
You could speed up the process of magnetizing your needle by stroking it with one end of your magnet.
In either case, if you consider the 'needle floating on surface tension' to be too difficult, you can pierce a small bit of cork or polystyrene foam with your needle, and float that.

What else can I help you with?
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.
How far do you need to keep a magnet from a compass?
The compass needle is magnetic so if you place a magnet near the compass, the needle will change direction either attracting or reppeling.
What happens when a compass is brought closer to a magnet?
When a compass is brought closer to a magnet, the compass needle will align itself with the magnetic field of the magnet. This alignment occurs because the magnetic field of the compass interacts with the magnetic field of the magnet, causing the needle to point towards the magnet.
Is a compass needle essentially a magnet?
Yes, a compass needle is essentially a magnet because it aligns with the Earth's magnetic field due to its magnetic properties.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
What is the magnet in a compass?
The compass needle.
What is a example of a magnet?
A compass needle.

Why does the needle of a compass point south when it's put on a bar magnet?
When a compass needle is placed near a bar magnet, it aligns itself with the magnetic field created by the magnet. The compass needle is a small magnet itself, with its north pole attracted to the south pole of the bar magnet and repelled by its north pole. If the compass needle points south, it indicates that the bar magnet's south pole is near the compass's north pole, demonstrating the fundamental property of magnetic attraction and repulsion. Thus, the orientation of the compass needle reflects the magnetic field direction of the bar magnet.
What does a compass does when it detects a magnet?
The needle goes to the magnet because of the pull!!!
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
Is the magnet in a compass a permanent magnet or a electromagnet?
It is a permanent magnet. Electromagnets(as the name suggests) requires an electric source to become a magnet, when the power source is turned off it will not function as a magnet.
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.
Why won't a compass work near a magnet?
The compass needle is itself a magnet which is why it always points north according to the earth's magnetic field. If you place a magnet (Whose magnetic power is stronger than the earth's) close to the compass its needle will be attracted t the magnet and not to the North Pole.
