Induction cooktop

Hi..

I am an industrial design student, currently undertaking my final year project which is on kitchen unit that has an induction cooktop integrated in it. However, after long search, I still couldn't find any information on the parts that make an induction cooktop.

I have to know the details of the parts. So far what I could get is just a very rough diagram showing an electromagnetic coil and an eletctric generator. Does anyone have any information on the detail of the parts?

Thank you so much for the help. Need the info urgently, project is due soon:(
