![]() The back EMF technology opposes the voltage that powers the motor to reduce its effectivity. The running motor of the hairdryer consists of a coil that turns into a magnetic field. They are implementing this technology in hairdryers, which comes up with in-built electromagnetic fields that oppose the direction of the generated EMF back to their source.Īre you wondering about how does this Back EMF technology do the job? The most neoteric edition of technology now is the Back EMF or Counter EMF. They are developing new technologies in their labs to decrease the amount of EMF radiation, so health-conscious people can effortlessly keep their anxiety away. In recent years, many hair tool manufacturers have come up with the idea of reducing the effects of EMF emission from the hairdryers and other electrical devices. The United States Environmental Protection Agency (EPA) suggests the range of 0.5 to 2.5 mG as the recommended safety levels. So, you can see the exposure of EMF radiation from hair dryers varies from 60 to 20000 milli-gausses, which is pretty high and may prove to be damaging enough to cause fatal health issues. It denotes the average amount of EMF produced by our day-to-day appliances in the mG unit. The electromagnetic fields produced in electrical appliances are measured in the mG (milli-gauss) unit by EMF testers, which varies with the distance the device is kept from it. The rotating coil generates moving charge (or current) to create magnetic fields that overlap with the electrical force caused by the anions. The solenoid of a hairdryer motor is the core of its EMF production. Hairdryers are commonly corded tools that are high in EMF radiations. ![]() ![]() Machines don’t cease to radiate even when they’re shut yet plugged in. Virtually no electrical device is free of EMF radiation. And despite corded tools emit relatively lower frequency EMF radiation, they are nowhere far from affecting the cells of our brain and body. Almost all types of wireless devices produce high-frequency EMF, which alludes to Radiofrequency as well. This force is called EMF, and it may cause emission of faint lines of both high-frequency and low-frequency radiation.Įvery kind of electrical device produces EMF be it wired or wireless. In an electrical device, when a static charge produces an electrical field, and a moving charge (current) creates a magnetic field, they both interact to form a unique force. It refers to Electro-magnetic Field, which is a combined force of electrical and magnetic fields. Low EMF Hair Dryer – Buyer’s Guide What is EMF?ĮMF is a term derived from physics.
