Use of a magnet in our everyday life.

Electronics and magnets.

In computers magnets are employed for recording information, for example, on memory cards. Magnets change the direction of magnetic material on the data carrier in segments, which then depict binary data. Later the computer interprets the profile from all the recorded segments of magnetic material and processes them into data recognizable to every user. In miniature speakers , which you encounter in laptops, televisions or radios just as employ magnets. Mounted in the speaker, a wired coil and magnet change electronic signals into sound vibrations.

Electric energy and other branches.

Magnets provide us with a rich repertoire of applications in the world of industry. In electric generators, they exchange mechanical energy into electricity, at the same time electric motors employ magnets to transform electric energy again into mechanical energy. During recovery, electromagnets in cranes catch and move big segments of metal, some of which weighing thousands of kilograms. Mines use magnetic separators to isolate necessary metal ores from pulverized rock. In food processing, such magnetic separators eliminate minuscule pieces of metal from cereals as well as various granular or liquid food products. Farmers raising cattle use magnets to catch pieces of metal that cows are able to consume while grazing. A cow eats the magnet together with food. It's definitely not a joke. As the magnet moves through the animal's digestive system, it captures small pieces of metal.

Health and medicine at work and home.

Magnets are found in specific commonly used medical devices, such as magnetic resonance imaging machines. They employ a strong magnetic field to obtain a radar radio signal from inside the body, employing the signal to form a strong, detailed view of bones, organs, and remaining tissues. The magnet in such devices is extremely strong - thousands of times stronger than ordinary kitchen magnets. Another therapeutic purpose of magnets is the treatment of tumors. The specialist administers a magnetically sensitive solution into the tumor area and then employs a powerful magnet to release thermal energy in the infected area. The high temperature eliminates cancer cells without damage 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 - neodymium magnet, which is available from us or MW 12x4 / N38 - neodymium 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?

Although it most likely is not obvious, to you, but in a most homes you will discover many magnets. Fridge magnets keep papers, bottle openers as well as personal minuscule objects attached on typically metal refrigerator doors. A pocket compass employs a magnetic needle to show the direction north. The black magnetic strip on the reverse side of a credit card collects personal details in the identical way, as a computer hard disk. Hoovers, food processors also washing machines possess electric motors, which work thanks to the application of a magnet. Magnets can be found in phones, alarms and in toys for children. Our existence all around us is full of magnets.
