Computers and electronics.

In computers magnets are utilized for recording information, for example, on hard drives. Magnets modify the direction of magnetic substance on the data carrier in segments, which then present binary data. Subsequently the computer recognizes the direction from each segment of magnetic material and decodes them into data recognizable to the ordinary user. In tiny speakers , which you encounter in computers, televisions as well as radios also employ magnets. Situated in the speaker, a wired coil and magnet change electronic signals into sound vibrations.

Electric energy as well as subsequent branches.

Magnets demonstrate a wide array of applications in many fields 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 recovery, electromagnets in hoists catch and transfer large pieces of metal, some of which weigh thousands of kilograms. Mines employ magnetic separators to isolate necessary metal ores from pulverized rock. In the food industry, such magnetic separators exclude small elements of metal from seeds , and also various granular possibly liquid food items. Ranchers raising cattle employ magnets to catch pieces of metal that cows can consume in the pasture. A cow swallows the magnet along with the food. It's definitely not a jest. As the magnet travels through the animal's organism, it captures small pieces of metal.

Magnets in health service at home and work.

Magnets are found in some commonly used medical devices, such as magnetic resonance imaging machines. They exploit a strong magnetic field to produce a radar radio signal from inside the body, using the signal to create a clear, detailed view of bones, organs, and remaining tissues. The magnet in such devices is very effective - thousands of times more potent than ordinary household magnets. Another medical use of magnets is the treatment of tumors. The specialist injects a magnetically sensitive solution into the tumor region and then uses a strong magnet to release thermal energy in the affected area. The thermal energy eliminates 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 - 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.

Every day with a magnet?

Probably it might be not obvious, to you, but in a your apartment you will discover many magnets. Fridge magnets keep notes, bottle openers and other minuscule objects suspended on metal refrigerator doors. A handy 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, technologically speaking, way, as a computer hard disk. Hoovers, food processors also washing machines have electric motors, which operate thanks to the use of a magnet. Magnets are in phones, doorbells and in toys for children. The world surrounding us is filled with magnets.
