Applications of magnets in our daily life.

Throughout the day, you frequently encounter magnets more than once without realizing it. They play an essential role in a diverse range of devices, from ordinary plush toys, headphones and speakers to credit cards to professional tools such as equipment for magnetic resonance imaging. The size of magnets varies from just noticeable spots to factory monsters the size of a wardrobe. These large ones are clearly perceptible, the tiny ones more than once tucked away inside numerous accessories of household, office, medical, or commercial use, carrying out their own mission in silence and remaining at the same time absolutely imperceptible.

Electronics and magnets.

In laptops magnets are employed for collecting data, for example, on memory cards. Magnets modify the direction of magnetic substance on the hard disk in segments, which subsequently depict binary data. Subsequently the computer reads the course from each segment of magnetic material and decodes them into data understandable to the average user. In miniature speakers , which are found in computers, televisions or radios also employ magnets. Situated in the speaker, a wire coil and magnet change electronic signals into sound vibrations.

Not just electric energy.

Magnets offer a broad array of applications in many fields of industry. In electric generators, they transform mechanical energy into electricity, simultaneously electric motors use magnets to change electrical energy in reverse into mechanical energy. During recovery, electromagnets in cranes grab and transfer large pieces of metal, some of which weighing thousands of kilograms. Mines use magnetic separators to separate valuable metal ores from pulverized rock. In the food processing, such magnetic separators exclude minuscule fragments of metal from grains as well as remaining fine-grained possibly liquid food goods. Cattle farmers use magnets to pick out fragments of metal that cows might consume while grazing. A cow swallows the magnet together with food. It's definitely not a joke. As the magnet travels through the animal's digestive tract, it picks up small pieces of metal.

Medicine and health at home and work.

Magnets are found in specific commonly operated medical devices, such as magnetic resonance imaging machines. They employ a intense magnetic field to generate a radar radio signal from inside the body, exploiting the signal to compile a strong, precise picture of bones, organs, and remaining tissues. The magnet in such devices is extremely effective - thousands of times more powerful than ordinary kitchen magnets. Another therapeutic use of magnets is the treatment of tumors. The physician administers a magnetically sensitive fluid into the tumor zone and then uses a strong magnet to release thermal energy in the affected area. The heat destroys cancer cells without loss 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?

Even though it might be not visible, to you, but in a your apartment you can encounter magnets magnets. Fridge magnets keep notes, bottle openers as well as personal tiny souvenirs suspended on metal refrigerator doors. A handy compass employs a magnetic needle to show the way north. The black magnetic strip on the reverse side of a credit card saves data in the same, technologically speaking, way, as a computer hard disk. Vacuum cleaners, blenders and washing machines possess electric motors, which function thanks to the application of a magnet. Magnets operate in phones, alarms also in toys for children. Our existence all around us is full of magnets.
