Coils, covered with impact resistant plastic so that they are safe to touch, for use as primary or secondary coils in combination with the transformer core D (1000976). With safety connection sockets.
As secondary coils these can output either low or high voltage, depending on the primary voltage, and therefore they cannot be used in student experiments.
