There are scores of items in an average household that require a
regular supply of electric current for their operation, while others
need to be recharged periodically, such as laptops, tablets, mobile
phones, electric toothbrushes, mp3 players, and shavers etc. We have got
so used to these gadgets that it is difficult to imagine living without
them. The one thing associated with all these devices is an electric
cable and the larger is the number of such devices, the more are the
cables. Unfortunately, any bunch of tumbled dusty wires creates a very
ugly sight. Moreover, they can be hazardous and present the risk of your
tumbling over them, unless you are careful. The introduction of
wireless chargers, which eliminate the use of wires, is a blessing, as
by using them, one can operate or recharge many devices.
It is already known that, with the help of electromagnetic fields we can transfer energy between two close objects, located close to each other, even without connecting the two through wires. When we pass electric current through an electric wire, an electromagnetic field is established around that electric wire. Instead of using a straight wire, if we use a wire in the form a coil, we can amplify the magnetic field. By positioning another coil close to the former, the magnetic field induces a current in the secondary coil. That is basically the principle of operation of wireless chargers, where the energy is transmitted to the primary coil of the charging unit. As a result, an electromagnetic field is formed, which in turn induces a current in the secondary coil of the device that need to be charged. That is why wireless charging is also termed "inductive charging".
Since the two coils, meaning the primary and the secondary, are not interconnected, it is feasible for the electromagnetic field, set up in the primary coil of a charging device, to induce voltage in the secondary coil. It implies that, if we had more than one secondary coil, all coils would receive induced voltage from the primary coil. That is the underlying principle of modern wireless chargers that allow you to recharge multiple gadgets at the same time. Now, you can procure a wireless charger that will simultaneously charge your camera, your mobile phone and your music player.
Wireless chargers are easy to use and known to be safe as long as they are used according to the instructions of the manufacturer. You are not exposed to any risks of harmful radiations. This is a very safe and efficient option for charging various devices. Wireless chargers eliminate the need of plugging-in so often! They will automatically charge any mobile device falling within their range.
