Demand for magnets in our ordinary life.

Electronics and computers.

In laptops magnets are used for storing information, for example, on memory devices. Magnets modify the direction of magnetic substance on the hard disk in segments, which then present binary data. Later the computer recognizes the direction from all the recorded segments of magnetic material and processes them into data readable to the ordinary user. In small speakers , which are found in computers, televisions and radios just as employ magnets. Installed in the speaker, a wire coil and magnet change electronic signals into sound vibrations.

Electric energy as well as subsequent branches.

Magnets provide us with a broad repertoire of implementations in the world of industry. In electric generators, they convert mechanical energy into electricity, while electric motors exploit magnets to transform electrical energy in reverse into mechanical energy. During recycling, electromagnets in lifts catch or move big pieces of metal, some of which weigh thousands of kilograms. Mines employ magnetic separators to separate valuable metal ores from crushed rock. In food processing, such magnetic separators exclude minuscule pieces of metal from cereals , and also various fine-grained or liquid food products. Ranchers raising cattle employ magnets to pick out bits of metal that cows can consume while grazing. A cow eats the magnet along with the food. It's certainly not a prank. As the magnet moves through the animal's digestive tract, it captures small pieces of metal.

Medicine and health at home and work.

Magnets are found in specific commonly used medical devices, such as magnetic resonance imaging machines. They exploit a intense magnetic field to generate a radar radio signal from inside the body, using the signal to create a strong, complete view of bones, organs, and other tissues. The magnet in such devices is very strong - thousands of times more potent than typical kitchen magnets. Another therapeutic application of magnets is the treatment of tumors. The specialist administers a magnetically sensitive fluid into the tumor zone and then uses a strong magnet to produce thermal energy in the contaminated area. The heat kills cancer cells without harm 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 - neodymium magnet, which is available from us or MW 12x4 / N38 - neodymium 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.

Magnet in household use?

Although it may be not obvious, to you, but in a your apartment you will discover a lot of magnets. Fridge magnets keep papers, bottle openers as well as other minuscule souvenirs hung on typically metal refrigerator doors. A portable compass uses a magnetic needle to determine the route north. The black magnetic strip on the back of a credit card collects data in the identical, technologically speaking, way, as a hard disk in a computer. Hoovers, blenders and washing machines have electric motors, which operate thanks to the application of a magnet. Magnets can be found in phones, alarms also in children's toys. Our existence around us is filled with magnets.
