Hello. This is the circuit of high power magnetic pulser I'm working on - 
Simple circuit with neon bulb triggering SCR works fine. I just tried to use digital pulse generator instead. My power resistors are only rated @ 25W and they get quite warm (approx 65 C). Also, I found my AWG 16 coil getting warm and perhaps AWG 14 would be better choice. I just used what I had on hand. Personally, I like to keep things simple and there is nothing wrong with neon trigger. Anyway, I'm not done with it yet but I thought to share anyway.
Update: I made a short YT about that and uploading now but it may take 6hrs to appear due to my kids online activities

) so please be patient.
I'm just looking for best and simplest way to make this pulser. I made this coil couple years ago for different experiment and decided to give a try. Despite the look it is quite easy to wind but it has unique vortex shaped field coming from the center while very weak on the circumference. In other words, it contains the field in it instead of spreading around. Anyway, just an experiment. I'm planning to test this device on plants and make a pad with few coils connected together so each seedling will be exposed to equal field.
