Demand for magnets in our everyday life.

Electronics and computers.

In computers magnets are used for recording data, for example, on memory devices. Magnets change the direction of magnetic substance on the data carrier in segments, which thereafter depict binary data. Subsequently the computer interprets the profile from all the recorded segments of magnetic material and processes them into data recognizable to the average user. In miniature speakers , which you encounter in computers, televisions or radios too use magnets. Installed in the speaker, a wired coil and magnet transform electronic signals into sound vibrations.

Electric energy , and also subsequent industries.

Magnets demonstrate a rich repertoire of implementations in the world of industry. In electric generators, they transform mechanical energy into electricity, simultaneously electric motors exploit magnets to convert electrical energy again into mechanical energy. During recycling, electromagnets in cranes catch and transfer heavy elements of metal, sometimes weigh thousands of kilograms. Mines use magnetic separators to clean useful metal ores from crushed rock. In the food industry, such magnetic separators remove small fragments of metal from seeds and remaining granular possibly liquid food goods. Farmers raising cattle employ magnets to capture fragments of metal that cows might eat while grazing. A cow ingests the magnet along with food. It's certainly not a joke. As the magnet moves through the animal's digestive tract, it picks up particles of metal.

Health and medicine at home and work.

Magnets are found in certain commonly applied medical devices, such as magnetic resonance imaging machines. They use a strong magnetic field to produce a radar radio signal from inside the body, exploiting the signal to form a clear, precise image of bones, organs, and other tissues. The magnet in such devices is exceptionally effective - thousands of times stronger than common kitchen magnets. Another medical application of magnets is the treatment of tumors. The specialist administers a magnetically sensitive solution into the tumor zone and then uses a strong magnet to generate thermal energy in the contaminated area. The thermal energy 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?

Probably it may be not noticeable, to you, but in a regular home you will discover a lot of magnets. Magnets on refrigerators keep papers, bottle openers as well as strange small souvenirs suspended on metal refrigerator doors. A portable compass employs a magnetic needle to show the way north. The dark magnetic strip on the back of a credit card stores data in the identical way, as a hard disk in a computer. Hoovers, food processors as well as washing machines utilize electric motors, which work thanks to the employment of a magnet. Magnets are in phones, alarms and in model cars. Our existence all around us is filled with magnets.
