You can make plate magnets from two combinations of rare earths. These elements have come to replace all the previous materials used to make these types of magnets. Rare earth magnets are superior in nearly all respects when compared to magnets made from iron or alloys that incorporate iron. These newer magnets were only invented in the 1960’s.
The term ferro fluid refers to a liquid made of microscopic, ferromagnetic particles which acquires a powerful magnetism in the presence of another magnetic field. The particles are known as nanoparticles because of their extremely small size. These fluids are artificially produced in industrial settings. Each particle receives a coating of surfactant. This is a special compound that reduces surface tension and inhibits clumping among the ferromagnetic particles. The particles have a tendency to remain evenly spread throughout the fluid and resist settling. There are many types of applications for these fluids.
The world can be a dangerously loud place, but many people do not do enough to protect their hearing form the effects of loud noises. In the United States, for instance, it is estimated that 10% of the population suffers from some kind of hearing loss. Though loss of hearing caused by increasing age is the most common type, hearing loss caused by exposure to excessive noise is a serious problem. Being around noise is often more harmful than many people realize, which is why people do not always use the proper protection. However, hearing loss caused by noise is almost completely preventable. Companies like MSA Sordin make products designed to prevent hearing loss by mitigating the effects of loud noises. These products can be used by anyone, and they are a terrific investment for those interested in hanging onto their hearing for a long time.
DSLR cameras are expensive gadgets. Much like any other electronic device, they are prone to damage from extreme differences in temperature, weather conditions and shock. Pelican Cases, silica gels, rain sleeves, camera armor and a neutral density filter are only some of these devices. Most cost a bundle to buy but keeping your device clean and safe during your trip is worth the extra investment.
Since the dawn of time, early man used cave drawings to communicate messages to others. Thus, the idea of using visual imagery to communicate an idea is not new. While modern-day communications have evolved beyond writing on the wall, colorful, visual displays in unexpected locations can still be immensely powerful. Delivering a message in a colorful, creative way is a challenge faced by individuals and businesses alike. Regardless of the type of magnet or promotional idea, custom magnets are a relatively inexpensive way to convey a message and make the idea stick.

Somewhere in the 60s, scientists at NASA were trying to find out ways of controlling liquid substance in space. The only thing possible was to create a magnetic fluid, which would respond to a magnetic field, and thus enable control. The result of this research was the creation of ferrofluid, which had extremely tiny magnetic solid particles suspended in a medium of liquid.
It is no secret that working on a construction site can be dangerous. Whether you are a professional or you are an amateur remodeling your home, it is important that you have the proper safety gear before you set foot on the site. While it may seem that there is an infinite number of types of safety equipment, safety can be broken down into a few main categories: the eyes, the ears and the respiratory system. By making sure that you have a good pair of goggles, high-quality Peltor headsets and a working respirator, you may prevent injuries that could affect you for the rest of your life.
