There are scores of things in an average home that require a regular supply of electric current for their function, while others need to be recharged occasionally, such as laptops, mobile phones, tablets, mp3 players, and electric toothbrushes, shavers, etc. We have got so utilized to these gadgets that it is hard to imagine living without them.
The one thing connected with all these gadgets is an electric cable and the larger is the number of such gadgets. Unfortunately, any bunch of dropped dusty wires creates a very ugly view. That is why the latest hidden wireless charger has been introduced through wireless technology which is now in very much demand.
Moreover, wired chargers can be dangerous and present the chance of your tumbling over them, unless you are alert. The introduction of wireless chargers, which eradicate the use of wires, is a blessing, as by utilizing them, one can operate or recharge multiple devices
It is already understood that with the assistance of electromagnetic fields we can assign energy between 2 close objects, located close to each other, even without joining the 2 through wires. When an electric current is passed through an electric wire, an electromagnetic field is formed around that electric wire.
Rather than using a straight wire, if we utilize a wire in the form of a coil, we can strengthen the magnetic field. By positioning another coil relative to the former, the magnetic field induces a wind in the secondary coil. That is essentially the principle of function of wireless chargers, where the energy is transferred to the direct coil of the charging unit.
As a result, an electromagnetic field is created, which in turn causes a current in the secondary coil of the appliance that needs to be charged.
