Demand for magnets in our ordinary life.

Electronics and magnets.

In computers magnets are employed for recording data, for example, on hard drives. Magnets change the direction of magnetic substance on the hard disk in segments, which thereafter present binary data. Subsequently the computer recognizes the profile from each segment of magnetic material and processes them into data readable to every user. In small speakers , which you encounter in computers, televisions and radios also use magnets. Installed in the speaker, a twisted copper insulated wire coil and magnet change electronic signals into sound vibrations.

Electric energy as well as next fields.

Magnets demonstrate a wide array of uses in the world of industry. In electric generators, they exchange mechanical energy into electricity, simultaneously electric motors employ magnets to change electrical energy again into mechanical energy. During recycling, electromagnets in hoists lift and transfer heavy segments of metal, sometimes weighing thousands of kilograms. Mines use magnetic separators to separate valuable metal ores from pulverized rock. In the food industry, such magnetic separators eliminate minuscule fragments of metal from cereals , and also various powdery or liquid food products. Cattle farmers employ magnets to pick out bits of metal that cows might ingest while grazing. A cow ingests the magnet along with food. It's certainly not a joke. As the magnet travels through the animal's organism, it catches particles of metal.

Medicine and health at work and home.

Magnets are found in some commonly applied medical devices, such as magnetic resonance imaging machines. They use a strong magnetic field to produce a radar radio signal from inside the body, employing the signal to form a strong, precise image of bones, organs, and other tissues. The magnet in such devices is very strong - thousands of times stronger than typical household magnets. Another therapeutic use of magnets is the treatment of tumors. The physician injects a magnetically sensitive solution into the tumor area and then uses a powerful magnet to produce thermal energy in the contaminated area. The high temperature kills 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.

Every day with a magnet?

Although it most likely is not obvious, to you, but in a most homes you will discover many magnets. Fridge magnets hold notes, bottle openers as well as personal tiny souvenirs hung on metal refrigerator doors. A handy compass uses a magnetic needle to indicate the way north. The black magnetic strip on the back of a credit card collects information in the identical, technologically speaking, way, as a computer hard disk. Hoovers, blenders and washing machines utilize electric motors, which function thanks to the employment of a magnet. Magnets can be found in phones, doorbells as well as in model cars. Our existence surrounding us is filled with magnets.
