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.

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.
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.
Infer what characteristic of a compass needle accounts for your observation of the compass and the magnet?
because the gravity of the earth
Why does a compass spin when it is placed next to a magnet?
A compass needle is a small magnet itself. When it is placed next to a larger magnet, the magnetic field of the larger magnet interacts with the magnetic field of the compass needle. This interaction causes the compass needle to align with the magnetic field of the larger magnet, causing it to spin and point in the direction of the magnetic field lines.
What is the magnet in a compass?
The compass needle.
What is the moveable bar in a compass called?
A compass magnet or a compass needle.
What is a example of a magnet?
A compass needle.
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.
Is a needle in a compass a permanent magnet?
Yes, it is a permanent magnet.
What does a compass does when it detects a magnet?
The needle goes to the magnet because of the pull!!!

Is A compass needle permanent a magnet?
Compass needles are permanent magnets. in response to the Earth's magnetic field, the compass needle will point toward the geographic North Pole.

In what way is the earth a giant magnet?
In that it has a magnetic field - which can be detected by a compass needle.
