Applications of magnets in our daily life.

Electronics and magnets.

In computers magnets are utilized for collecting information, for example, on memory cards. Magnets transform the position of magnetic substance on the hard disk in segments, which then depict binary data. Later the computer recognizes the course from each segment of magnetic material and processes them into data readable to the average user. In miniature speakers , which you encounter in computers, televisions or radios just as employ magnets. Installed in the speaker, a wire coil and magnet change electronic signals into sound vibrations.

Not just electric energy.

Magnets offer a rich arsenal of implementations in the world 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 recovery, electromagnets in hoists grab and transport large elements of metal, some of which weigh thousands of kilograms. Mines use magnetic separators to clean useful metal ores from pulverized rock. In food processing, such magnetic separators remove small fragments of metal from cereals and various fine-grained or liquid food items. Cattle farmers employ magnets to capture fragments of metal that cows are able to eat in the pasture. A cow eats the magnet together with food. It's absolutely not a joke. As the magnet moves through the animal's digestive tract, it captures bits of metal.

Magnets in health service at home and work.

Magnets are found in specific commonly used medical devices, such as magnetic resonance imaging machines. They employ a strong magnetic field to produce a radar radio signal from inside the body, employing the signal to compile a clear, complete picture of bones, organs, and remaining tissues. The magnet in such devices is exceptionally intense - thousands of times more potent than common kitchen magnets. Another medical purpose of magnets is the treatment of tumors. The specialist injects a magnetically sensitive fluid into the tumor area and then uses a powerful magnet to generate thermal energy in the affected area. The thermal energy eliminates 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.

In a house where magnets are used?

Although it might be not obvious, to you, but in a most homes you can encounter many magnets. Magnets full of refrigerators support papers, bottle openers as well as strange tiny souvenirs suspended on metal refrigerator doors. A handy compass utilizes a magnetic needle to show the way north. The dark magnetic strip on the reverse side of a credit card collects personal details in the identical way, as a computer hard disk. Vacuum cleaners, blenders also washing machines utilize electric motors, which function thanks to the employment of a magnet. Magnets are in phones, alarms also in model cars. The world all around us is filled with magnets.
