rub it many times with a magnet
Yes, because it takes about 50 strokes in the same direction
Rub the iron needle along one direction on the strong bar magnet repeatedly until it becomes magnetized. Make sure to always rub it in the same direction to ensure a consistent magnetic field. This process aligns the magnetic domains within the iron needle, causing it to become permanently magnetized.
The idea is to line up the electrical fields of the atoms, and to do that you have to stroke in one direction or the other. However, whether you stroke left to right or right to left doesn't matter.
It call Rutilled Quartz, there are two kind of this stone rutilled with gold needle and black needle, the best stone is from Iraq and almost rutilled quartz from there are black needle..... IMHO
When one end of the unmagnetized needle is in contact with a magnet, the magnetic field from the magnet induces magnetism in the needle. This results in the end of the needle touching the magnet becoming a magnetic pole, and the other end becoming an opposite pole. The opposite poles attract each other, causing the unmagnetized needle to attract another needle when in contact with a magnet.
To magnetize a needle, you can rub it against a magnet in the same direction multiple times. This will align the magnetic domains in the needle and make it magnetic.

magnetize a needle by rubbing it on a magnet. Lie the needle in a shallow container of water, allowing the surface tension to keep the needle afloat. The needle will orient to north and south
You can magnetize a needle by rubbing it against a magnet in one direction multiple times. This process aligns the magnetic domains within the needle to create a magnetic field. Alternatively, you can use a strong electrical current to induce magnetization in the 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.
Oh, what a lovely idea! To make a simple plotting compass, all you need is a magnet, a small piece of cork, a needle, and a shallow dish of water. Just magnetize the needle by rubbing it against the magnet, then carefully place it on the cork floating in the water. The needle will align with the Earth's magnetic field, helping you find your way and create beautiful drawings in nature. Just remember to handle everything with care and have fun exploring the world around you!
Copper is not a magnetic material and does not magnetize easily.
Rub the needle across a magnetic surface...always in the same direction, don't go back and forth. This will magnetise the needle. Then float the needle in a dish of water. And presto you have your own compass
for this you need an iron pin, a magnet and a plastic cap that can float on water. Magnetize the iron pin by rubbing a magnet on it continuously in one direction for about 15 minutes. Now place the needle in the centre of the plastic cap and hold it in position with cello tape. take a container containing water and put the cap in it such that it floats on it. The pin will always point in north south direction. but the compass can be confused by a magnet placed near it.
The best way to find and purchase a sewing machine replacement needle is to check the model number of your sewing machine and then search for compatible needles online or at a local sewing supply store. Make sure to choose the correct size and type of needle for your specific sewing machine model.
the best attracton in America is the space needle. the space needle is in seattle.
You can magnetize a paper clip by passing it repeatedly over a large magnet.
