Magnetic Systems

People know that a special kind of rock can draw the same kind of rock and iron pieces themselves, suspended in ancient times. This rock is called Rode stone. Today, humans use the same force exerted by electromagnets and permanent magnets to provide magnetic support for trains and more efficient generators. This report focuses on the use of magnets in power generation and magnetic assisted trains. Magnetic force is defined as the force exerted by a magnetic field.

The product I want to see first is a magnetic washing system. This system works by placing two magnets inside the washing machine. These magnets have the same effect as detergent in water, so you can clean your clothes. Does it sound crazy? Contrary to the many negative comments I read, there are many science behind it. Both ends of a detergent molecule make it possible to break through the surface tension of water. At the end of detergent molecules adhering to fat (fat) repels water molecules. It is called hydrophobic, which means "damage by water". By trying to get away from the water molecule, the hydrophobic end of the detergent molecule is pushed up to the surface. This weakens hydrogen bonds that hold water molecules on the surface. As a result, the surface tension of water is interrupted. - How do you break detergent surface tension?

Next, we will introduce several refereed papers supporting the theory that magnets change the surface tension of water. It is noteworthy that many critics who criticize the magnetic laundry system say there is no evidence to support the science behind the product. If you take time to read this research, the missing one is not evidence of found, but it is a necessary equipment to properly measure the surface tension of water. The surface tension of the yttrium oxide - air interface was accurately measured under a magnetic field of up to 10 T. At 10 T, the surface tension increased by 37 ± 0.14 mN / m (3.30 ± 0.19%). It was found that the surface tension increases linearly. As the square of the magnetic field increases, its proportionality constant shows a significant isotope effect.
