Demand for magnets in our everyday life.

Electronics and magnets.

In computers magnets are employed for collecting data, for example, on memory devices. Magnets transform the direction of magnetic substance on the data carrier in segments, which then depict binary data. Subsequently the computer interprets the profile from each segment of magnetic material and converts them into data understandable to the average user. In miniature speakers located in computers, televisions and radios too employ magnets. Mounted in the speaker, a wired coil and magnet process electronic signals into sound vibrations.

Not just electric energy.

Magnets demonstrate a wide arsenal of implementations in many industries of industry. In electric generators, they exchange mechanical energy into electricity, simultaneously electric motors employ magnets to transform electric energy again into mechanical energy. During recycling, electromagnets in lifts grab or transport large elements of metal, sometimes weigh thousands of kilograms. Mines use magnetic separators to isolate useful metal ores from pulverized rock. In the food processing, such magnetic separators remove small pieces of metal from cereals and other granular or liquid food goods. Farmers raising cattle employ magnets to capture fragments of metal that cows can eat in feed. A cow eats the magnet along with its feed. It's certainly not a jest. As the magnet shifts through the animal's digestive system, it captures small pieces of metal.

Magnets in health service at work and home.

Magnets are found in some commonly operated medical devices, such as magnetic resonance imaging machines. They employ a powerful magnetic field to obtain a radar radio signal from inside the body, exploiting the signal to form a clear, precise view of bones, organs, and remaining tissues. The magnet in such devices is exceptionally strong - thousands of times stronger than ordinary kitchen magnets. Another medical purpose of magnets is the treatment of tumors. The specialist administers a magnetically sensitive fluid into the tumor area and then employs a strong magnet to generate thermal energy in the contaminated area. The high temperature eliminates 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.

Magnet in household use?

Probably it may be not obvious, to you, but in a your apartment you can encounter many magnets. Magnets full of refrigerators keep notes, bottle openers and also other minuscule items hung on typically metal refrigerator doors. A portable compass utilizes a magnetic needle to show the route north. The black magnetic strip on the reverse side of a credit card collects information in the same, technologically speaking, way, as a computer's hard drive. Vacuum cleaners, blenders as well as washing machines have electric motors, which work thanks to the employment of a magnet. Magnets can be found in phones, alarms and in model cars. The world around us is filled with magnets.
