How can I magnetize a needle?
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.
How do you magnetise a needle?
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.
Jalil has a magnet and two needle. The magnet attracts both needles but the needles fo not attract each other. He strokes one needle with the magnet. What happens when he moves the two needles near ea?
The needle that was stroked by the magnet will become magnetized and attract the other needle. The unmagnetized needle will not be affected, so it will not attract the other needle.
How to find the north side of a magnet without a compass?
To find the north side of a magnet without a compass, you can use the floating needle method. Rub a needle on a magnet and place it on a small piece of paper floating in water. The needle will align itself with the Earth's magnetic field, pointing north.
When you rub a magnet with metal what happens to the metal object?
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
How do you do a needle?
You need to rub the needle with a magnet or you can use coil around the needle and pass current to make it a electro magnet.

How do you make a needle magnetic?
rub against needle with strong magnet i guess 1. Hold a needle by the eye and stroke it gently 30 times with your magnet, in the same direction. Do the same with the second needle, making sure that you use the same end of the magnet. 2. Test your needle-magnets on some pins before you use them for other experiments.

How can you magnetise an iton needle permanently using a strong bar magnet?
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.
When you rub a magnet with metal what happens to the metal object?
When you rub a magnet with metal, the metal object becomes temporarily magnetized. This happens because the atoms in the metal align with the magnetic field of the magnet. However, once the magnet is removed, the metal object loses its magnetism.
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.
Why would a hiker carry a magnet and a string?
Using a magnet, string and needle you can create a crude but workable compass. Method Get a needle or a very small nail and a bar magnet. Also get some thread or a bowl of water and two tiny pieces of cork. Hold the needle in one hand and the magnet in the other. Put the North end of the magnet against the needle in the middle and rub it towards and off the point. Lift the magnet up and away from the needle and place it in the middle again. Repeat rubbing the North end of the magnet against one half of the needle 20 times or so. Flip the magnet over so you are using the South end and rub it from the middle to the 'eye' end of the needle 20 times. You have magnetized the needle just like a compass needle. Hanging Compass Tie one end of a length of thread to a stick and the other end to the middle of the needle. Balance is important Let the needle hang freely and slide the thread to a point on the needle where it balances level. Lower the needle into a wide-mouthed jar and lay the stick across the opening to prevent wind interference. Watch which way your compass needle turns. It should always settle to the same direction.
What is the best way to magnetize a needle?
Rubbing a magnet along the needle in one direction will align the needle's magnetic domains and magnetize it. For stronger magnetization, repeat the process multiple times in the same direction. Be cautious when handling magnets to avoid accidental demagnetization.
What happens when you stroke a needle 20 times with a magnet?
it becomes magnetic :)
