I am attempting to modify an existing inductive charging coil (Palm Touchstone) so that it outputs the correct magnetic flux for a different wireless charging standard (Qi). I am doing this as an experiment but need help to calculate what the actual magnetic flux of the coil is. and figure out how to modify its properties.
I know that the input is 5v with 1amp at 60hz and I know that the receiving coil gets roughly 3v of power when put close to the charger. The Qi charging base takes the same input (5v, 1A, 60hz) but I know the surface area of the charger is different and I'm sure the receiving coil is also different. Full specification of the Qi standard can be found here and I am more than willing to take apart the touchstone to get any information needed to make this happen. I'm curious what it would take.
Is it possible to modify the properties (increase the magnetic flux) of the charging coil by simply pushing more volts or amps through the charging coil? Or would that require more wire loops or a different receiving coil?
