“How can we charge a device without a cord?”

 

When we think about charging electrical devices, we typically think of using a huge power supplying power cord. However, is it possible to charge without having any physical connection? Well, let’s use our engineering mindset to figure it out. We know that if we were to take two inductive coils, put them close together, and send an electric coil to one, then a current will be induced in the other. So what if we were to have a station with one inductive coil, and a device with another, every time the electromagnetic activity of the station can induce a current in the other? Well, this is known as wireless charging and is a very rapidly developing technology, with voluminous implications for both electric vehicles and cell phones.
