Right, and if you bend and mold the iron pot into the shape necessary to conduct it somewhere useful (like chemical energy storage) rather than just turn to heat, you will find than an array of micro coils will hardly work at all.
There are grid-array tiny coil wireless energy devices, but the grid is used to find a "best fit" coil depending on the alignment of the device to be charged, and then uses just that coil.
Again, a cast iron pot acts as a single huge shorted secondary turn. And a shit one at that (hence why it gets so hot), otherwise the primary (the cook top) would burn up too. You want the opposite of this for electrical energy transfer (low loss, low heat)!

I'd probably lose my job if I didn't know this
