No. It only needs to pass through a magnetic field to become magnetized. It does not need to come into physical contact with the magnet producing that field. This is because the process of magnetization has to do with electromagnetic induction rather than physical contact.
You can perform a simple experiment at home to prove this point. You'll need a bar magnet, a paper clip, and a thin sheet of paper. Place the paper between the magnet and the clip. Rub the clip against the paper on top of the magnet, and observe that the clip will still become magnetized even though it is not in physical contact with the magnet.
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.
Move towards the U magnet so that the poles attach.
The stroke method is a mechanical process used to magnetize materials. It involves stroking a magnet along a particular material in a specific direction to align the atomic domains within the material and induce magnetism. This method is commonly used to create temporary magnets.
because the magnet causes particles called electrons in the atoms of the nail to align along the magnet's lines of force. The atoms with aligned electrons then act like tiny bar magnets themselves.
A piece of any magnetic material, like iron or steel (a nail, knitting needle, bolt etc.) is take and placed on a bench or a table. A bar magnet is brought close to the magnetic material (say an iron piece AB). One end of the bar magnet is stroked against it, moving from end A to end B of the iron piece. When the bar reached end B, it is lifted and the stroke is repeated from A to end B. This procedure is repeated several times, keeping two things in mind: (a) The same pole of the bar magnet should be used every time (b) Strokes should be in the same direction By stroking the iron piece with the north pole of the bar magnet, end A becomes the North Pole, and end B the South Pole. If you bring the South Pole of any magnet close to end A now, what will you observe? You will observe that the two attract, which simply proves that end A acquires the North Pole.
You can remagnetize a magnet by rubbing a good magnet along the bad one. Do this a few times. Be sure to rub the magnet in only one direction.
One way to create a permanent magnet is by aligning magnetic domains in a ferromagnetic material by exposing it to a strong magnetic field and then cooling it to set the alignment. Another method involves rubbing a piece of iron or steel along a magnet to align the domains in the material and create a weak permanent magnet.
The stroking method involves repeatedly stroking a magnet in the same direction along a piece of metal to align the domains of the metal and magnetize it. This process helps induce magnetism in the metal by aligning its domains with the magnetic field of the magnet. It is a simple and effective technique to create temporary magnets.
The magnetic properties of a temporary magnet are derived from the fact that its molecules are aligned along the magnetic polarity: they mostly point in the same direction and so one end of the temporary magnet is North and the other is South. Banging the magnet can knock some of these molecules out of alignment so that they face random directions. As a result, there is no particular direction in which is then North and South and so magnetism is reduced. When enough molecules have been knocked out of alignment you are left with a demagnetised piece of metal.

There are a few ways . . . 1. Point the screwdriver north and south, then tap on it for a while with a hammer or other steel device. 2. Rub the screwdriver for its entire length with a magnet for a while.
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.
To magnetize a quarter, you can rub a strong magnet along its surface in one direction for several strokes. This aligns the metal's magnetic domains, which can induce a weak magnetism in the coin. It's important to use a strong enough magnet, like a neodymium magnet, for effective magnetization. However, keep in mind that the effect will be temporary and the coin will not retain strong magnetism.
The magnet is in the world because magnetism is one of the fundamental forces of the universe, along with gravity.

Real quick FYI, temporary magnets are also called electromagnets :) A really simple electromagnet is an iron nail with with copper wire (can be insulated or uninsulated) wrapped around it. At the ends, attach a 9-volt battery to the negative and positive terminals. And voila! To "turn-off" the magnetism, just remove one of the ends from the terminal.
