![]() Other people can talk on their bluetooth device all day and don’t notice any ill effects. Some people are very sensitive to EMF exposure and have to take special, and sometimes extreme, precautions to live in this very EMF-rich world. The old adage “the dose makes the poison” may be very true for EMF exposure it’s tricky because it will vary from person to person. We are undergoing a great experiment that no other civilization has ever faced. We’re exposed to 100 million times greater artificial EMF radiation than our grandparents, and that exposure grows each year. This was after a series of studies showed a soft correlation between EMFs and a type of brain cancer. So much so that the World Health Organization classified EMFs as “possibly carcinogenic to humans” back in 2011. There is a growing body of scientific evidence showing that too much EMF exposure can be harmful to our health. This EMF-infused technology has become a way of life for many of us. Our children play with our cell phones or use electronics to learn and play. Most of us live in a home with our Wi-Fi on 24/7, a smart meter attached to the outside of our living room wall, and sleep with our iPhone by our heads. Unfortunately, there aren’t a ton of conclusive studies on this topic, which is a shame because we are literally bombarded with them daily. People are starting to take notice to this potential health issue. We can get a Wi-Fi signal just about anywhere, and so many of us walk around with multiple personal EMF devices like cell phones, smart phones, and laptop computers. But, now, it’s a whole different ballgame. This kind of EMF exposure comes from our phones, our cars, power lines, laptops, cellphone towers, wifi, and even our blenders and toaster ovens!ĮMFs have been under the radar up until the last decade or so because they weren’t as prevalent. The Earth also has a natural magnetic field and there are electric fields in the atmosphere.īut, usually when we refer to EMF exposure and health risks, we are talking about the electric-magnetic fields that come from our electrical devices. Our bodies have electric and magnetic fields that are associated with our nervous and muscular systems. The nearness of the horseshoe magnet’s poles facilitates the ability to use these magnet keepers more easily than other types of magnets.EMFs, or electromagnetic fields, are invisible areas of energy or lines of force that emanate from matter. A magnetic field holds its strength best when the entire magnetic field is given the ability to loop through a ferromagnetic substance instead of air. ![]() To increase the coercivity of horseshoe magnets, steel keepers or magnet keepers are used. Coercivity is weaker in disc or ring shapes, slightly stronger in cylinder or bar shapes, and strongest in horseshoe shapes. This is due to coercivity also known as the "staying magnetized" ability of a given magnet. The shape of the horseshoe magnet also drastically reduces its demagnetization over time. A horseshoe magnet is stronger because both poles of the magnet are closer to each other and in the same plane which allows the magnetic lines of flux to flow along a more direct path between the poles and concentrates the magnetic field. Over time it became the universal symbol for all magnets. ![]() The shape of the magnet was originally created as a replacement for the bar magnet as it makes the magnet stronger. This would lay the groundwork for development of the electrical telegraph and the future of world-wide telecommunications for the next century and more. Sturgeon showed that he could regulate the magnetic field of his horseshoe magnet by increasing or decreasing the amount of current being run through the wires. This was also the first practical electromagnet and the first magnet that could lift more mass than the magnet itself when the seven-ounce magnet was able to lift nine pounds of iron. These experiments culminated in William Sturgeon wrapping wire around a horseshoe-shaped piece of iron and running electric current through the wires creating the first horseshoe magnet. Following this discovery, many other experiments surrounding magnetism were attempted. In 1819, it was discovered that passing electric current through a piece of metal deflected a compass needle.
