Demand for magnets in our everyday life.

Computers and electronics.

In laptops magnets are employed for collecting data, for example, on memory cards. Magnets change the direction of magnetic substance on the hard disk in segments, which subsequently depict binary data. Later the computer reads the direction from all the recorded segments of magnetic material and converts them into data recognizable to the ordinary user. In small speakers located in computers, televisions as well as radios also employ magnets. Mounted in the speaker, a wired coil and magnet change electronic signals into sound vibrations.

Magnets are everywhere.

Magnets provide us with a rich array of applications in many industries of industry. In electric generators, they transform mechanical energy into electricity, simultaneously electric motors exploit magnets to change electric energy back into mechanical energy. During recycling, electromagnets in hoists catch and transport heavy elements of metal, some of which weigh thousands of kilograms. Mines use magnetic separators to separate necessary metal ores from crushed rock. In the food industry, such magnetic separators eliminate small elements of metal from grains as well as remaining fine-grained possibly liquid food items. Cattle farmers employ magnets to pick out pieces of metal that cows can consume while grazing. A cow ingests the magnet along with the food. It's definitely not a prank. As the magnet travels through the animal's organism, it picks up particles of metal.

Medicine and health at home and work.

Magnets are found in certain commonly applied medical devices, such as magnetic resonance imaging machines. They exploit a strong magnetic field to obtain a radar radio signal from inside the body, using the signal to form a perfect, complete view of bones, organs, and remaining tissues. The magnet in such devices is extremely intense - thousands of times stronger than ordinary household magnets. Another therapeutic application of magnets is the treatment of tumors. The physician administers a magnetically sensitive fluid into the tumor zone and then employs a powerful magnet to generate thermal energy in the contaminated area. The thermal energy destroys cancer cells without loss 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.

Every day with a magnet?

Even though it might be not obvious, to you, but in a your apartment you will find a lot of magnets. Fridge magnets support papers, bottle openers and also strange tiny souvenirs hung on typically metal refrigerator doors. A portable compass utilizes a magnetic needle to determine the way north. The dark magnetic strip on the back of a credit card collects personal details in the same way, as a computer hard disk. Vacuum cleaners, blenders as well as washing machines possess electric motors, which function thanks to the use of a magnet. Magnets are in phones, alarms also in toys for children. The world surrounding us is full of magnets.
