Hi Langer,

```
Planck's equation represents the energy for a photon. Light is an EM wave just of very high frequency compared to what many think of as an EM wave and a photon is the quantum unit for representing electromagnetic energy. Photons have behavior that both resembles particles and waves. For the frequencies of your TC, the quantum energy level will be very very small and doesnt really represent what, I believe, your question is refering to. Radient flux??? Not sure what you are really meaning here. Magnetic fields are created by moving charge (dynamic electric fields). Electric fields are created by dynamic magnetic fields. The two are interlinked. There is moving charge in the TC and this of course creates a magnetic field. This, however, does not mean that it radiates significantly since the physical dimensions of the coil are very very small compared to the wavelength of 259KHz. Its radiation efficiency is very small. Most of the fields created by the TC are near fields that drops off very rapidly with distance from the source.

Hello, I am wondering how one would go about calculating the radiant flux emitted from a topload.
```
```
I considered using Planck's hypothesis (E = hv) using Planck's constant and frequency, but i dont know if thats completely accurate? I know that is for particle energy, but how would you go about calculating wave energy? (I know it should be same). If radiant energy and wave energy is different (theoretically it shouldnt be..) then what would be the formula for radiant flux? If there is another completely different method of calculating energy:
```my coil-
secondary = 21mH
primary = 48uH
primary voltage = 8.4kV
resonant frequency = 259kHz

Thanks for all the help!
