I need to project a solenoid. But i have some questions: - How much need to be thick enamelled copper? How i can calculate the thickness necessary? (to not burn solenoid wire) - Will be good enamelled alluminium too? This if i suppose to power it with 10A, 2000turns. And: - How i can power the coil?(where i can find or build a generator to give me 10A costant current?) - How i can build a generator(or multiple generators) to power multiple solenoids with this high current? - Where i can find or buy a good plunger, it need to be magnetic or metal(what type of metal)? With full core? Thank you.
