You are probably watching this show via a device that has a battery, lap tops, mobile phones, alls of these things need charging and for the moment we still using cords and plugs for this.
Inductive charging or wireless charging isn’t new, it’s been used since the early 90’s in electric toothbrushes and for surgically implanted devices like artificial hearts. You have even heard this in the pop culture in the late 1800, Tesla was allegedly able to power light bulbs with no wires and claimed to be able to transmit power from one location to another wirelessly. This is something we can explain… I guess…
Wireless Inductive Charging gets it’s name from the magnetic field interaction called Induction. Inside of the charging pad and the inductive charging device are tiny coils of wire.
The pad being plugged into the wall is fully powered and that power is cycling at 60 Hz per second. When the other coils come within a short distance their Flux will interact the Flux in the device move the electrons around and charge the battery.
