molested_cow:

As I understand your design is basically to create a heating element for non-ferrus containers right? So won’t it function the same a a steel key attached by a piece of string?

I did a school project which was a portable induction cooker. Nowhere near perfect cus untimately, it was limited by material and shape.

Induction works by generating a field of EM waves. The rate of change of flux( meaning the cutting action of waves on the ferrus material) will determine the heat generated. Thus, the larger the contact surface area of the material and the wave, the more heat it generates. So your device being small, probably will be pretty inefficient when used on a big cooktop.

Your friend’s induction cooker’s power saving feature is a 0n/off feature. What I was hoping to see is a self power adjusting feature. Best if the cooker can self direct the field to concentrate the waves to a certain area where the container is, thus to achieve max efficiency.

That reminded me of my project. I had 3 zones of field generators to cater for different heating style purposes. This implies that I can chose to use a particular zone according to the size of my pot/pan.

…yes you could use a steel key and a string… doh

as i can see you have more expierences in induction. so i can forget these infos about self directed field size. i just grap that up somewhere…

so… thanx for the help! i learned alot in a few hours! thnx to all!
