Utilizations of magnets in our ordinary life.

Electronics and magnets.

In laptops magnets are utilized for storing information, for example, on memory devices. Magnets change the position of magnetic material on the data carrier in segments, which thereafter present binary data. Later the computer recognizes the direction from each segment of magnetic material and converts them into data recognizable to the ordinary user. In miniature speakers , which are found in laptops, televisions as well as radios too employ magnets. Mounted in the speaker, a wired coil and magnet process electronic signals into sound vibrations.

Not just electric energy.

Magnets provide us with a broad repertoire of applications in many fields of industry. In electric generators, they exchange mechanical energy into electricity, simultaneously electric motors employ magnets to transform electric energy in reverse into mechanical energy. During recovery, electromagnets in hoists lift and transport heavy pieces of metal, some of which weigh thousands of kilograms. Mines employ magnetic separators to separate valuable metal ores from broken rock. In the food processing, such magnetic separators exclude tiny fragments of metal from grains and remaining granular or liquid food goods. Cattle farmers use magnets to pick out bits of metal that cows might ingest in the pasture. A cow swallows the magnet together with its feed. It's absolutely not a jest. As the magnet shifts through the animal's digestive system, it catches particles of metal.

Medicine and health at home and work.

Magnets are found in certain commonly operated medical devices, such as magnetic resonance imaging machines. They use a intense magnetic field to obtain a radar radio signal from inside the body, exploiting the signal to create a clear, detailed picture of bones, organs, and other tissues. The magnet in such devices is extremely effective - thousands of times more potent than typical kitchen magnets. Another therapeutic application of magnets is the treatment of tumors. The doctor administers a magnetically sensitive fluid into the tumor region and then employs a powerful magnet to produce thermal energy in the infected area. The heat eliminates cancer cells without harm to healthy tissues.
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.

In a house where magnets are used?

Although it most likely is not obvious, to you, but in a your apartment you can encounter a lot of magnets. Fridge magnets hold notes, bottle openers and also other minuscule items attached on typically metal refrigerator doors. A pocket compass uses a magnetic needle to show the direction north. The black magnetic strip on the back of a credit card collects personal details in the same way, as a hard disk in a computer. Vacuum cleaners, blenders also washing machines possess electric motors, which work thanks to the use of a magnet. Magnets operate in phones, doorbells and in toys for children. Our existence all around us is filled with magnets.
