Good day and thanks for looking at my post. 
I will get down to the business at hand.
I am at the drawing board trying to design a compact device that will produce a powerful electromagnetic field for a short period of time, say 5 seconds or so. My intention is to create a device that can produce a saturation effect in a ribbon of metal.
My understanding is that my device will be limited by the following design features:
1. the wound core. (material)
2. the winding itself and its number of turns.
3. the power supply.
4. the way in which the power flows thru the winding.
5. 9v-18v 6000mah
I have so many questions but for now i will only ask a few.
a. in making the turns around the core i intended on using very small gauge wire with the insulation still on it so that as i form the turns it does not short across "loops" effectively lessening the number of turns. will this disturb or inhibit the transfer of energy to the core in an appreciable way? thoughts?
b. instead of connecting the device straight to a battery i intend on using an arduino board to control external switches, these switches are intended to control a seperate circuit (the EMC circuit) I am wondering if a can 1. use capacitors to discharge large voltages thru the winding or 2. create something similar to the HEI ignition system (ie. using the high backfed voltages of low voltage circuits being opened and closed. option one seems more likely to work.
and finally
C. what is the ideal core to use in this inexpensive project? a simple iron bar or bolt?
