i am currently working on a project that requires energy harvesting ,so i decided to use electromagnetic induction for the purpose. However I can not decided how to design my magnet and coil combination. All i know is i want 2.6-3.3v and 26mA for round about 4 ns.
The setup in brief required a movable permanent magnet and a stationary coil. The moment of the permanent magnetic is like a oscillating pendulum just for once but with a sleed of say about 15km per hours.
So can you please suggest me how should i start designing.
