I have noticed that there are ferrite stripes on the bottom of induction cooking plates, where are they for?
I tought maybe they are for the purpose of keeping the field away from the electronics, if so, we can use them to.
somebody knows ?

Probably usable but not helpful in view of slight conductivity to very high voltage. Besides a Tesla coil is an AIR-CORED resonant high voltage transformer.
I have made a Ferrite "TC" about 35 years ago.
From my website: " I later developed this idea with an old transformer (probably 15kV/25mA) from a dump which in retrospect was an old unpotted NST (neon sign transformer). I used a single static gap with a 12 inch ferrite cored coil of 11 primary and 100 turns secondary giving 2 inch sparks with 26 small ceramic capacitors with 2 strings of 13 x 10 nF at 2.5 kV each. It ran nicely for about 20 years! Years after I made it I heard that Tesla had beaten me to that discovery by quite a few years! This photo is a mock up with most of the original parts."
