Neodymium magnet - marking of poles eNeS.
eNeS magnets "N and S" - what poles do neodymium magnets have?
Neodymium magnets have poles marked as "N" (North) and "S" (South). "N" indicates the north pole, while "S" indicates the south pole.
In the case of using neodymium magnets as components of generators or magnetic motors, the better pole depends on the design and requirements of the device.
In other applications, such as promotional magnets or mounting magnets, the difference between poles is usually insignificant. What matters is how strong the magnet is and its size.
It is also important to note that neodymium magnets are very strong but highly sensitive to high temperatures, which can result in a permanent decrease in magnet strength or a complete loss of that strength.
- you have to pay a commission, which increases the price compared to a specialized store,
sellers often have limited knowledge about magnet properties, which can lead to fraud or selling low-quality products,
there is no possibility to check the quality of magnets before purchase because sellers do not have appropriate measuring devices.
For these reasons, before deciding to buy neodymium magnets on online platforms, it is worth considering purchasing them from a specialized magnet store like dhit.pl or their OLX auction, which has proper measuring devices, specialists with knowledge and experience in this field, and generally competitive prices.
There is also a theory of the existence of unipolar magnets. So far, this type of unipolar magnet has not been found on Earth. This elementary magnet, called a magnon by scientists, is said to exist in space, awaiting discovery. However, this theory has not been confirmed.
Use a compass - the N pole attracts the compass needle to the geographic north, and the S pole to the south. In compasses, the N pole is usually marked with red, and the S pole with blue.
Use metal objects - metal objects will be attracted to the N and S poles of the magnet.
Use a magnetic watch - this type of watch contains a magnet and indicates the direction of the N and S poles.
Conduct a resistance measurement - you can measure the electrical resistance in the magnet and determine which is the N pole and which is the S pole.
Use an old CRT television - turn on the television and place the magnet against the screen. If the magnet is strong, lines indicating the N and S poles of the magnet should appear on the screen.
Use a smartphone with a compass app - you can download a compass app on your smartphone and use it as a compass. The app will show the direction indicator for the N and S poles.
These are a few ways to mark the N and S poles of a magnet.

The N designation represents the north pole of the magnet, while S represents the south pole of any magnet. When two magnets with the same poles are brought close to each other, the neodymium magnet will repel the other magnet. However, if magnets with opposite poles are brought close to each other, they will attract each other.
Already in ancient times, it was observed that some objects attract other objects. Depending on the material of the object, a magnet attracts all objects made of iron or alloys of rare earth metals that are affected by the magnetic field, with a constant force.
It was also noticed that any object made of iron can acquire additional properties when placed within a strong magnet. However, they will never permanently gain magnetic properties this way. They can acquire them if exposed to a strong magnetic field for a long time.
In this way, you can create a strong neodymium magnet.
Samarium-cobalt magnets: They are made from samarium and cobalt, making them very durable and temperature-resistant. They can reach a magnetic energy product of up to 35 MGOe.
Alnico magnets: They are made from aluminum, nickel, iron, cobalt, and zinc. They are very durable but less powerful than neodymium magnets, reaching a magnetic energy product of only up to 12 MGOe.
Ferrite magnets: They are made from iron oxide and ceramic magnetic materials. They are 10 times weaker than neodymium and samarium-cobalt magnets but are cheaper and easier to produce. They can reach a magnetic energy product of up to 5 MGOe.

Electronics: Magnets are used in speakers, televisions, computers, hard drives, electric motors, and other electronic devices.
Transportation: Magnets are used in electric motors of vehicles such as trams, trains, subways, hybrid and electric cars.
Medicine: Magnets are used to create magnetic resonance imaging (MRI) images for diagnosing and monitoring various diseases.
Industry: Magnets are used for metal separation, flow control, storage, and transportation.
Home: Magnets serve as door locks, handles for lifting objects, and are used in refrigerators to keep the doors tightly closed.

Heat the magnets above 80 degrees Celsius - high temperature weakens the magnetic force and allows for easy separation of the magnets.
Use a wooden tool to separate the magnets - a special tool allows for precise separation of the magnets without the risk of damaging their surfaces.
Remember that neodymium magnets are very strong, so caution should be exercised when disconnecting them to avoid cuts or other injuries. Important! Do not put magnets in your pocket - it may result in castration!
In case of difficulties in disconnecting magnets, consult a professional who has the proper tools and knowledge to safely disconnect neodymium magnets.
