It should not be removed, the surface of enameled wire itself with an insulating layer, its diameter specifications, size tolerance requirements is different from general wires.

Scrape it with a knife to see if it has fallen off.
Burn it down to see if there is a bright flame.Or connect the wire from the surface to the circuit to see if it works
