I am an eleventh grade student currently in AP Physics C. My teacher did a demonstration with an electromagnet where he drew AC current from the wall to shoot a conductive ring. I was wondering where i could find the blueprint for such a device, or perhaps receive some guidance on how many coils i need/how much current i need to shoot a ring to a certain height.
( )
out of curiosity, is it possible to do the same with dc current. for example, maybe i could use some D cell batteries connected in series, a capacitor, and the device i talked about above for just a magnetic pulse rather than oscillating magnetic flux.
what about just batteries connected in series?
(i've already tried that but with not nearly enough coils. since i didnt have any resistors and the wires were relatively thick, I only connected the circuit for a fraction of a second, because i didn't want the circuit to short out)
And some questions that weren't answered in my lessons:
how does the difference between thick and thin wires affect the device? (i do know that usually as cross sectional area increases resistance decreases)
i can't think of any more questions atm
If i seem like I'm completely loss or my logic is all muddled up, please don't just point it out, but also try to correct me so that i may learn something.
Cheers from the high school student that feels like he doesn't know enough physics.
