Is there any problem if the ferrites are in contact with the induction coil?
If the top side contact with the coil, the coil quality must be very good to avoid short,
To prevent the short problem, there usually be two way out:
1. We usually use insulation tape with good thermostability,
there is a example for you(please refer to the black tape)
2. You can use the plastic in between the ferrite and coil, there is simple to save labor cost,
