Applications of magnets in our daily life.

Computers and electronics.

In computers magnets are employed for collecting data, for example, on memory devices. Magnets modify the direction of magnetic material on the data carrier in segments, which thereafter depict binary data. Later the computer reads the course from all the recorded segments of magnetic material and converts them into data understandable to the average user. In miniature speakers , which you encounter in computers, televisions as well as radios too employ magnets. Installed in the speaker, a twisted copper insulated wire coil and magnet transform electronic signals into sound vibrations.

Electric energy and other branches.

Magnets provide us with a wide repertoire of uses in many industries of industry. In electric generators, they exchange mechanical energy into electricity, at the same time electric motors use magnets to convert electric energy again into mechanical energy. During recycling, electromagnets in hoists catch and transfer large segments of metal, some of which weighing thousands of kilograms. Mines use magnetic separators to clean useful metal ores from pulverized rock. In food processing, such magnetic separators remove minuscule fragments of metal from cereals and remaining powdery or liquid food items. Cattle farmers employ magnets to capture bits of metal that cows can consume in feed. A cow eats the magnet together with food. It's definitely not a jest. As the magnet travels through the animal's digestive system, it captures particles 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 use a strong magnetic field to obtain a radar radio signal from inside the body, using the signal to form a clear, detailed picture of bones, organs, and other tissues. The magnet in such devices is extremely intense - thousands of times stronger than typical hobbyist magnets. Another therapeutic purpose of magnets is the treatment of tumors. The doctor injects a magnetically sensitive fluid into the tumor zone and then employs a strong magnet to produce thermal energy in the contaminated area. The high temperature kills 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.

Every day with a magnet?

Although it most likely is not visible, to you, but in a regular home you will discover magnets magnets. Fridge magnets keep papers, bottle openers and also other small objects attached on typically metal refrigerator doors. A handy compass utilizes a magnetic needle to indicate the route north. The dark magnetic strip on the reverse side of a credit card stores personal details in the same way, as a computer's hard drive. Hoovers, food processors and washing machines possess electric motors, which operate thanks to the application of a magnet. Magnets are in phones, alarms and in toys for children. Our existence surrounding us is full of magnets.
