New Physics Video Playlist - How Does Wireless Charging Work?

This science and technology video explains how wireless charging works. Energy is transferred from the charger to the phone by means of two coils of wire that must be in close proximity to each other. AC current is needed for energy transfer to occur. A constant current source won't make the cut. The current has to change constantly for energy to be transferred into the second circuit.
