In the lab where I work we have a potential niche application for a Helmholtz coil pair that can be swept from 0 to a peak value between 100G and 1000G over a 100ns pulse. The smallest size the coil can be is 1" in both diameter and height. Using AWG 20 wire and the smallest possible coil dimensions, this would mean a peak current of ~2.3 amps.

The issue we're worried about is the impedance of the coil making it impossible to pulse that quickly. I know that with the right lumped passive elements we can impedance match to the coil to make it pass the lowest harmonic of the pulse with no problem, but it would still disperse the higher harmonics and the pulse would not work. Are there practical workarounds or techniques for pulsing reactive loads with an appreciable amount of power?

Thanks in advance!
