In the old days it was said that there is Mount Magnit at the end of the world. She stands by the sea. Trouble for a ship that sails too close. The mountain attracts iron, so much so that it pulls out all the nails from the boards! The ship breaks apart and sinks.

In fact, there are mountains of magnetic ore in the world. We had one of the largest in the Urals, near the city of Magnitogorsk. It was, because now a deep abyss yawns in its place. The mountain was blown up in parts, and the fragments were raked in by excavators and loaded into wagons. And not one of the steel excavators, not one of the steel wagons stuck to the mountain! So she gradually migrated to the blast furnaces of "Magnitka" - the Magnitogorsk Iron and Steel Works. The plant "pulled" the mountain to itself and destroyed it!

Magnetic ore does not attract so much. The artificial magnet is much stronger. It is cast from a special alloy and magnetized at the factory. Try to get such a magnet, you can do many interesting experiments with it. And first of all, of course, we will check if the magnet pulls the nails out of the ships.

Make a brigantine from a piece of cork or pine bark and stick a carnation into it. One and only, and even then a small one, otherwise the brigantine will turn over or even go to the bottom without any magnet. The carnation will also serve as a mast. Put a sail on it from a piece of paper. Let our magnetic brigantine raise the sails!

Animated pieces of iron

Well, now lower the brigantine into the water poured into a plate or basin, and pick up a magnet. Attach it to the side of the plate, just above the water. Do not wet the magnet: it will rust. Blow on the sail of the brigantine to get close to the magnet. Look: the brigantine is wrapping! The magnet turned her off the straight path and pulled her towards him. Click! The nail stuck to the magnet. But he didn't flinch. If you pull on the body of the brigantine, the stud will easily fall behind the magnet.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Photoelectric sensor Omron E3FZ 30.04.2009

Incorporating the same modular concept as Omron's popular E3Z series photoelectric sensor, the new E3FZ combines reliable object detection with a compact body and quick, easy installation.

Thanks to the innovative SecureClick mounting system, the new photoelectric sensors install ten times faster than most conventional rectangular sensors and three times faster than standard cylindrical sensors. The sensors are simply inserted into the appropriately drilled holes and snapped into place. Despite this speed and ease of installation, the SecureClick fastening system has been extensively tested to prove its reliability even at very high vibration levels.

The new sensors are made in the popular compact M18 cylindrical short body and are equipped with a high-brightness LED emitter that expands the boundaries of the measurement area. They are manufactured to tight tolerances, which ensures minimal optical axis deviation and simplifies system alignment.

Quick installation, easy set up and competitive pricing make these units particularly attractive for OEM applications, material handling systems and other demanding large scale applications.
