- TL;DR Summary
- I am trying to make an induction stovetop using some magnet wire. I understand how induction stovetops work but am less confident on the math I've done to design one. Can you double-check that I'm approaching this correctly?

I've been told an effective induction stovetop needs to deliver about 1000W of power. I have magnet wire that can tolerate at most about 0.2A of current, and was planning on using a 60Hz wall outlet as my source (obviously I'll need to bring down the outlet current quite a bit).

So the energy stored in an inductor is given by:

Which I assume would be roughly the same energy transferred to the pot when on the stove. So the power delivered would be

Then substituting P = 1000W and I = 0.2A I get that L = 1.2mH.

Then given that

So if I had a coil with 10 turns, the area would need to be about 10 times the length to deliver the power I need.

Am I doing this right? Did I mess up anywhere in my understanding?

So the energy stored in an inductor is given by:

**E = 0.5*I**^{2}*LWhich I assume would be roughly the same energy transferred to the pot when on the stove. So the power delivered would be

**P = E / t = E*(60 Hz)**Then substituting P = 1000W and I = 0.2A I get that L = 1.2mH.

Then given that

**L = μ**, I find that I need a ratio close to_{0}*N^{2}*A / ι**N**^{2}*A / ι = 952So if I had a coil with 10 turns, the area would need to be about 10 times the length to deliver the power I need.
