Demand for magnets in our daily life.

Electronics and computers.

In laptops magnets are used for collecting information, for example, on hard drives. Magnets modify the direction of magnetic material on the hard disk in segments, which subsequently represent binary data. Later the computer reads the direction from each segment of magnetic material and converts them into data readable to every user. In miniature speakers , which are found in laptops, televisions or radios too employ magnets. Installed in the speaker, a wired coil and magnet process electronic signals into sound vibrations.

Electric energy as well as subsequent industries.

Magnets provide us with a wide repertoire of implementations in the world of industry. In electric generators, they exchange mechanical energy into electricity, simultaneously electric motors exploit magnets to convert electric energy back into mechanical energy. During recovery, electromagnets in hoists grab as well as move large segments of metal, some of which weighing thousands of kilograms. Mines use magnetic separators to clean useful metal ores from broken rock. In food processing, such magnetic separators exclude minuscule pieces of metal from grains as well as other powdery possibly liquid food products. Farmers raising cattle use magnets to catch pieces of metal that cows are able to ingest in feed. A cow ingests the magnet together with food. It's absolutely not a joke. As the magnet travels through the animal's digestive tract, it captures small pieces of metal.

Medicine and health at work and home.

Magnets are found in certain commonly used medical devices, such as magnetic resonance imaging machines. They employ a intense magnetic field to obtain a radar radio signal from inside the body, using the signal to compile a strong, complete picture of bones, organs, and remaining tissues. The magnet in such devices is very effective - thousands of times more potent than ordinary kitchen magnets. Another medical purpose of magnets is the treatment of tumors. The doctor administers a magnetically sensitive solution into the tumor region and then uses a powerful magnet to release thermal energy in the infected area. The heat 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?

Even though it may be not noticeable, to you, but in a regular home you will discover magnets magnets. Magnets on refrigerators hold papers, bottle openers and also strange minuscule objects suspended 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 stores information in the identical way, as a computer's hard drive. Vacuum cleaners, food processors as well as washing machines possess electric motors, which operate thanks to the employment of a magnet. Magnets can be found in phones, alarms as well as in toys for children. Our existence around us is full of magnets.
