The very first Tesla coils were NT running his high frequency alternators
into standard laboratory induction coils.
Many of these coils had a core that could be slid in and out. After
removing the core NT noted the coil still operated (due to HF) and this lab
induction coil was a sec coil wound around a small large dia wire pri coil.
