![]() Second, the charging rate is slow-going compared to wires. This technology has a wireless charging distance of 30 feet without needing to be "paired up" to each charging device beforehand.

This is a major disadvantage versus a technology such as Wi-Charge. This is because the magnetic field the induction coil generates isn't that big, so you need to coddle the two coils together to get a flow going. While it was interesting that electrical energy can travel through the air, the technology is a little limited.įor one, the induction and receiver coils need to be mere millimeters apart from each other. It sounds like a scientific marvel of the 21st century, but again, we've known about this technology for over 100 years. Why Isn't Wireless Charging Technology Used Everywhere? The Insignia 20 W Qi Dual Wireless Charging Pad supports Qi wireless charging, so you can use it with phones, tablets, watches, and a whole lot more. ![]() You can then direct this electric current wherever it needs to go-like into your phone's battery, for instance. If a receiver coil is placed within the field, it takes the electromagnetic energy and turns it back into electricity. The induction coil turns the electric current into an electromagnetic field due to Oersted's law. To transfer electricity through the air, you can put an electric current through the induction coil and then place a receiver coil nearby. In this example, the best receiver happens to be yet another coil. ![]() You have to set up a receiver that can take this electromagnetic field and convert it back into an electric current. Of course, you can't just hold a battery in a magnetic field and expect it to charge up.

This little coil is what you'll find in a wireless charging pad-it's sitting there, converting an electrical current into an electromagnetic field, waiting for something to come along and "take" that energy. Inductive charging works by utilizing something called "Oersted's law." This states that when an electric current flows through a wire, it generates a magnetic field.Įven better, if you create a tight coil and run electricity through it, it creates an even stronger magnetic field. Using Coils and Oersted's Law to Transfer Energy So, what is wireless charging? This technology takes advantage of a technique called "inductive charging." This has been around since the late 19th century but didn't really take off until recent times. This wireless charging pad features black, white, or green marble, with unique, contrasting vein patterns for an opulent look.
