Demand for magnets in our daily life.

Computers and electronics.

In laptops magnets are employed for recording information, for example, on hard drives. Magnets change the direction of magnetic material on the hard disk in segments, which then depict binary data. Subsequently the computer interprets the profile from each segment of magnetic material and processes them into data understandable to every user. In small speakers , which you encounter in laptops, televisions and radios too use magnets. Installed in the speaker, a wired coil and magnet process electronic signals into sound vibrations.

Magnets are everywhere.

Magnets demonstrate a wide array of uses in many fields of industry. In electric generators, they convert mechanical energy into electricity, while electric motors use magnets to change electric energy back into mechanical energy. During recovery, electromagnets in lifts lift or transfer heavy pieces of metal, sometimes weigh thousands of kilograms. Mines use magnetic separators to isolate useful metal ores from pulverized rock. In the food industry, such magnetic separators exclude minuscule pieces of metal from grains as well as various powdery or liquid food goods. Cattle farmers use magnets to catch fragments of metal that cows are able to ingest in the pasture. A cow swallows the magnet along with food. It's certainly not a joke. As the magnet moves through the animal's organism, it catches small pieces of metal.

Medicine and health at home and work.

Magnets are found in some commonly applied medical devices, such as magnetic resonance imaging machines. They employ a intense magnetic field to produce a radar radio signal from inside the body, using the signal to compile a clear, precise image of bones, organs, and other tissues. The magnet in such devices is very effective - thousands of times more potent than typical household magnets. Another medical purpose of magnets is the treatment of tumors. The physician injects a magnetically sensitive fluid into the tumor area and then employs a strong magnet to produce thermal energy in the infected area. The heat eliminates 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 - 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 noticeable, to you, but in a your apartment you will find many magnets. Fridge magnets hold notes, bottle openers and also personal minuscule souvenirs attached on metal refrigerator doors. A pocket compass employs a magnetic needle to show the direction north. The dark magnetic strip on the back of a credit card collects data in the same way, as a computer hard disk. Hoovers, blenders as well as washing machines possess electric motors, which function thanks to the use of a magnet. Magnets can be found in phones, alarms and in model cars. The world around us is filled with magnets.
