Most power transformers contain an iron core and are designed to operate at
"power frequencies", ie, 50 or 60 Hertz.

While Nikola Tesla was experimenting with high frequency alternators he
discovered that at high frequencies, ie, above 10,000 Hertz, iron cores are
not necessary.  The electric currents begin to take on "wave-like"
properties and can propagate from the primary coil into the secondary coil
without an iron core.  In fact, they work best without an iron core.

By using a proper turns ratio and allowing the circuits to "resonate" at
high frequencies large potentials are developed.  These high frequency
transformers were named in honor of their inventor, "Tesla coils", also
known as resonance transformers.
