Demand for magnets in our everyday life.

Electronics and magnets.

In laptops magnets are used for collecting data, for example, on hard drives. Magnets change the position of magnetic material on the data carrier in segments, which subsequently represent 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 are found in laptops, televisions or radios also magnets are used in magnets. Installed in the speaker, a wired coil and magnet transform electronic signals into sound vibrations.

Not just electric energy.

Magnets provide us with a wide repertoire of uses in many fields of industry. In electric generators, they convert mechanical energy into electricity, while electric motors exploit magnets to change electrical energy in reverse into mechanical energy. During recycling, electromagnets in lifts grab as well as move heavy elements of metal, sometimes weighing thousands of kilograms. Mines use magnetic separators to clean valuable metal ores from pulverized rock. In food processing, such magnetic separators eliminate minuscule elements of metal from grains and other fine-grained or liquid food goods. Farmers raising cattle use magnets to catch bits of metal that cows are able to eat in the pasture. A cow eats the magnet together with the food. It's definitely not a prank. As the magnet travels through the animal's organism, it captures particles of metal.

Medicine and health at home and work.

Magnets are found in specific 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 create a strong, detailed view of bones, organs, and other tissues. The magnet in such devices is exceptionally effective - thousands of times more potent than ordinary hobbyist magnets. Another therapeutic application of magnets is the treatment of tumors. The physician administers a magnetically sensitive solution into the tumor zone and then employs a strong magnet to generate thermal energy in the affected 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.

Magnet in household use?

Probably it may be not obvious, to you, but in a regular home you will find magnets magnets. Fridge magnets support papers, bottle openers as well as personal small souvenirs suspended on metal refrigerator doors. A pocket compass employs a magnetic needle to show the way north. The dark magnetic strip on the back of a credit card stores personal details in the identical way, as a hard disk in a computer. Hoovers, blenders as well as washing machines possess electric motors, which function thanks to the employment of a magnet. Magnets operate in phones, alarms also in toys for children. The world around us is full of magnets.
