Utilizations of magnets in our ordinary life.

Electronics and computers.

In computers magnets are used for collecting information, for example, on memory cards. Magnets modify the direction of magnetic material on the data carrier in segments, which then depict binary data. Subsequently the computer reads the profile from all the recorded segments of magnetic material and decodes them into data recognizable to the ordinary user. In small speakers , which are found in laptops, televisions and radios too magnets are used in magnets. Installed in the speaker, a wired coil and magnet change electronic signals into sound vibrations.

Not just electric energy.

Magnets demonstrate a broad repertoire of implementations in the world of industry. In electric generators, they transform mechanical energy into electricity, at the same time electric motors exploit magnets to transform electrical energy in reverse into mechanical energy. During recovery, electromagnets in lifts catch as well as transport big elements of metal, sometimes weighing thousands of kilograms. Mines use magnetic separators to isolate valuable metal ores from crushed rock. In the food industry, such magnetic separators remove small pieces of metal from cereals and various powdery or liquid food products. Ranchers raising cattle use magnets to capture bits of metal that cows can ingest in the pasture. A cow eats the magnet along with food. It's certainly not a prank. As the magnet shifts through the animal's digestive tract, it picks up particles of metal.

Health and medicine at work and home.

Magnets are found in some commonly operated medical devices, such as magnetic resonance imaging machines. They use a powerful magnetic field to generate a radar radio signal from inside the body, using the signal to form a strong, detailed picture of bones, organs, and remaining tissues. The magnet in such devices is extremely intense - thousands of times more powerful than typical household magnets. Another medical use of magnets is the treatment of tumors. The doctor injects a magnetically sensitive fluid into the tumor area and then uses a powerful magnet to produce thermal energy in the infected area. The high temperature kills cancer cells without harm to healthy organs.
According to the president of the Polish Radiological Medical Society, the number of radiology specialists is currently insufficient. This field is rapidly developing and opens wide perspectives, so for those deciding on this profession, it is a quite far-sighted step. The demand for these specialists is growing in the job market, especially in the capital.
Jobs in Warsaw both in performing magnetic resonance imaging and in other positions in this field can be found on the Jooble job search engine page.

What can you do with a magnet and a battery?

With a magnet and a battery, you can build a simple homopolar motor. This type of direct current electric motor uses the principle of continuously cutting magnetic field lines with a conductor. In a homopolar motor, the conductor rotates around a fixed axis, being positioned perpendicular to a static magnetic field. As the force acting on the conductor is continuous and always directed in one direction, the motor does not require a commutator, but still needs slip rings. 'Homopolar' means that the electrical polarization of the conductor and the magnetic poles do not change, which means there is no need for commutation.
Want to do an amazing science project at home? Build your own homopolar motor! It's simple and a great way to demonstrate how electric current interacts with a magnetic field. Here's what you'll need:

Neodymium magnet: This is a very strong type of magnet that is key to the project. You can find it in electronic stores or online. For example, you can use a magnet with the product code MW 12x6 / N38 - cylindrical magnet, which is available from us or MW 12x4 / N38 - cylindrical magnet.
Battery: A standard AA or AAA battery will be perfect. Make sure it's new to have full voltage.
Copper wire: It must be clean and well-conducting. Copper wire can be found in an electronics store or you can recover it from unnecessary electronic cables.

Once you have gathered all the materials, bend the copper wire into a shape that allows it to rotate around the battery - it can be a simple 'U' shape or a spiral. Then place the neodymium magnet at one end of the battery, and position the bent ends of the wire so that one touches the magnet and the other directly touches the battery.
When you complete the assembly, the wire will start to rotate! You can experiment by changing the shape of the wire or using batteries of different voltages to see how it affects the speed of the motor's rotation. This is a fantastic way to learn through fun and experimentation.

Remember only to be cautious – neodymium magnets are very strong and should not be placed near electronic devices and magnetic media like credit cards or hard drives.

The strongest magnets, made from a mixture of neodymium, boron, and nickel, are known for their impressive pulling force, making them an ideal tool not only for industry but also for home applications. Whether it's for extracting tiny metal filings from an eye or searching for a lost needle in a haystack - our magnets are indispensable. We offer three main categories of neodymium magnets: cylindrical magnets, lamellar magnets, and annular magnets, each tailored to specific needs and applications. We invite you to explore our offer and discover how neodymium magnets can make your daily life easier.

Magnet in household use?

Probably it most likely is not noticeable, to you, but in a most homes you will discover many magnets. Magnets full of refrigerators support papers, bottle openers as well as other small souvenirs attached on typically metal refrigerator doors. A pocket compass uses a magnetic needle to show the direction north. The black magnetic strip on the reverse side of a credit card stores information in the identical way, as a computer hard disk. Vacuum cleaners, blenders as well as washing machines have electric motors, which function thanks to the application of a magnet. Magnets operate in phones, alarms as well as in model cars. Our existence all around us is full of magnets.
