Can someone tell me what the white paste is, where the coil touches the cooktop in an induction cooktop and what purpose does it serve?. This is a general question since the cooktops I have taken apart are similar. I'm curious as to if it is a vibration damper and may reduce a buzz that often occurs during operation. Thanks
