transfer electrecity wirelessly using electromagnetic inducton
I want to transfer electercity wirelessly using induction by electromagnetism, by using two solenoides, one source and one receiver. The receiver is connected to 8 (1.5V) leds and i need to light these leds wirelessly. please provide me what type of electrecity DC or AC must i use and what are the diameter of the coil, lenght.... and all these stuff. i need to light these leds at a distance of 20 Cm between the two coils. Provide me also formulas of calculation needed for this project and thank you.Please it is urgent and i needed for my University, it is graded. please and no need for raisonance .
