Applications of magnets in our daily life.

Computers and electronics.

In computers magnets are employed for recording data, for example, on memory cards. Magnets change the position of magnetic substance on the hard disk in segments, which thereafter present binary data. Later the computer recognizes the direction from each segment of magnetic material and converts them into data understandable to the ordinary user. In miniature speakers located in computers, televisions and radios also use magnets. Situated in the speaker, a twisted copper insulated wire coil and magnet transform electronic signals into sound vibrations.

Electric energy as well as next branches.

Magnets offer a rich arsenal of applications in the world of industry. In electric generators, they transform mechanical energy into electricity, at the same time electric motors employ magnets to convert electric energy again into mechanical energy. During recycling, electromagnets in cranes catch or transfer big pieces of metal, some of which weighing thousands of kilograms. Mines employ magnetic separators to separate valuable metal ores from pulverized rock. In the food processing, such magnetic separators remove tiny pieces of metal from cereals and remaining fine-grained or liquid food products. Farmers raising cattle employ magnets to pick out bits of metal that cows are able to consume while grazing. A cow swallows the magnet together with food. It's certainly not a jest. As the magnet shifts through the animal's digestive system, it captures bits of metal.

Magnets in health service at home and work.

Magnets are found in specific 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, exploiting the signal to create a perfect, complete image of bones, organs, and other tissues. The magnet in such devices is exceptionally effective - thousands of times more powerful than typical kitchen magnets. Another medical use of magnets is the treatment of tumors. The physician injects a magnetically sensitive fluid into the tumor area and then uses a strong magnet to release thermal energy in the contaminated area. The high temperature destroys 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 - 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 visible, to you, but in a regular home you will find many magnets. Fridge magnets hold papers, bottle openers and also strange small souvenirs attached on typically metal refrigerator doors. A handy compass utilizes a magnetic needle to determine the way north. The black magnetic strip on the back of a credit card saves personal details in the same, technologically speaking, way, as a hard disk in a computer. Vacuum cleaners, blenders as well as washing machines have electric motors, which work thanks to the employment of a magnet. Magnets are in phones, alarms as well as in model cars. The world around us is filled with magnets.
