[sdiy] Transformer question

[Bert Schiettecatte]

Hi All,

After getting a Braun 3D toothbrush I was impressed with the contactless
charging mechanism that was used. I went on the net and started
searching for some info and decided to try my own contactless charge
transfer DIY project. To start, I took two square bars of aluminum,
about 1cm x 1cm x 5cm in dimensions. I wrapped standard isolated solid
core wire around them (28 turns), I think the wire thickness is like 24
AWG or whatever the standard wire is used in solderless breadboards (a
little thicker than wire wrap wire). I was hoping to hook up one of the
two inductors I built to an AC power supply (say 5V, 500mA), and hook
the other one up to a multimeter measuring volts, then bringing the two
inductors close to each other and hoping to get some current or voltage
transferring from one inductor to the other one. Of course it doesn't
work. What am I doing wrong here? I am totally clueless in basic
electronics but I can program in C++ :-)

Any comments highly appreciated.
