Demand for magnets in our daily life.

Computers and electronics.

In computers magnets are utilized for storing information, for example, on hard drives. Magnets transform the direction of magnetic material on the data carrier in segments, which then present binary data. Subsequently the computer interprets the direction from all the recorded segments of magnetic material and processes them into data readable to the average user. In miniature speakers , which you encounter in computers, televisions or radios also employ magnets. Installed in the speaker, a wired coil and magnet process electronic signals into sound vibrations.

Magnets are all around us.

Magnets demonstrate a broad arsenal of applications in many industries of industry. In electric generators, they convert mechanical energy into electricity, simultaneously electric motors use magnets to convert electric energy back into mechanical energy. During recycling, electromagnets in hoists lift and move heavy segments of metal, some of which weighing thousands of kilograms. Mines employ magnetic separators to clean necessary metal ores from crushed rock. In food processing, such magnetic separators remove tiny elements of metal from cereals as well as other granular possibly liquid food products. Cattle farmers employ magnets to catch fragments of metal that cows can ingest while grazing. A cow eats the magnet together with the food. It's definitely not a prank. As the magnet shifts through the animal's organism, it captures small pieces of metal.

Health and medicine at work and home.

Magnets are found in certain commonly used medical devices, such as magnetic resonance imaging machines. They exploit a powerful magnetic field to obtain a radar radio signal from inside the body, employing the signal to compile a clear, detailed picture of bones, organs, and remaining tissues. The magnet in such devices is exceptionally effective - thousands of times more powerful than typical hobbyist magnets. Another therapeutic application 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 kills cancer cells without loss 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.

Every day with a magnet?

Even though it might be not noticeable, to you, but in a your apartment you will find magnets magnets. Magnets full of refrigerators hold papers, bottle openers and strange minuscule items attached on typically metal refrigerator doors. A portable compass employs a magnetic needle to indicate the route north. The black magnetic strip on the reverse side of a credit card collects data in the same, technologically speaking, way, as a hard disk in a computer. Vacuum cleaners, food processors and washing machines possess electric motors, which work thanks to the application of a magnet. Magnets operate in phones, alarms also in children's toys. Our existence all around us is filled with magnets.
