Applications of magnets in our ordinary life.

Computers and electronics.

In computers magnets are employed for storing data, for example, on hard drives. Magnets transform the direction of magnetic material on the hard disk in segments, which then represent binary data. Subsequently the computer reads the direction from each segment of magnetic material and decodes them into data recognizable to the average user. In tiny speakers , which you encounter in computers, televisions or radios just as magnets are used in magnets. Situated in the speaker, a wire coil and magnet transform electronic signals into sound vibrations.

Not just electric energy.

Magnets provide us with a broad array of uses in many fields of industry. In electric generators, they transform mechanical energy into electricity, while electric motors exploit magnets to transform electric energy in reverse into mechanical energy. During recovery, electromagnets in cranes grab and move large segments of metal, some of which weighing thousands of kilograms. Mines use magnetic separators to separate valuable metal ores from broken rock. In food processing, such magnetic separators eliminate minuscule elements of metal from cereals and other granular or liquid food items. Cattle farmers use magnets to capture bits of metal that cows can consume in feed. A cow eats the magnet together with the food. It's absolutely not a jest. As the magnet travels through the animal's digestive system, it catches small pieces of metal.

Health and medicine at home and work.

Magnets are found in some commonly applied medical devices, such as magnetic resonance imaging machines. They employ a intense magnetic field to produce a radar radio signal from inside the body, using the signal to form a perfect, precise image of bones, organs, and other tissues. The magnet in such devices is extremely intense - thousands of times more powerful than typical kitchen magnets. Another therapeutic use of magnets is the treatment of tumors. The specialist administers a magnetically sensitive solution into the tumor region and then uses a strong magnet to produce thermal energy in the contaminated area. The high temperature eliminates cancer cells without harm to healthy organs.
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 might be not visible, to you, but in a regular home you can encounter a lot of magnets. Fridge magnets support notes, bottle openers and personal small souvenirs attached on metal refrigerator doors. A portable compass employs a magnetic needle to indicate the route north. The black magnetic strip on the back of a credit card saves information in the same way, as a hard disk in a computer. Vacuum cleaners, blenders as well as washing machines utilize electric motors, which work thanks to the employment of a magnet. Magnets can be found in phones, alarms as well as in model cars. The world around us is full of magnets.
