The vertical coil has to be powered by variable AC from 50V to 75V .
Thank you to all of YOU for trying to help me.Dear "wvmarle" I do not know how to write the cod for Arduino. I try some programs written on ARDUINO playground, but no success for now. After reading all suggestion I came to a new schematic which I will attach . Could you please check it and if you think it will need some changes to work, please give me your opinion
.If you think the schematic will work I will really appreciate if some of you write and send me a code to upload on my Arduino
