No I mean how do the fields conserve energy.
For simple math, if i had a pipe with circumference of 1000 ft and a source of 414.8v, if i have 1 turn, the current will be 1 amp and i will have a field of 1 amp-turn.
If i have a coil with 2 turns, the resistance will be doubled and the current...
Ok, now I'm thinking of using a 12v pc power supply as it is more "renewable" than batteries.
My question now is if field is constant given with a given voltage and wire thickness, how does conservation of energy kick in and prevent me from using a coil with millions of coils and minimal...
The projectile is fixed because it is provided by my teacher when we run our devices in class so I can't change anything about that although the class ball looks darker than mine so it could be made of iron.
I am already using multilayers of wires and my coils are about an inch long with 400...
What I am doing is attracting the steel ball until it reaches the coil and then turning it off.
Why would magnetization be a bad thing on the steel ball and why would using mains power be dangerous when I already used 60 v dc without incident?
Also, on Wikipedia I read that field is...
It seems the simplest to use the arduino itself to charge the capacitor to 5v, using a resistor if you are worried about damage to the arduino.
To measure the discharging of the capacitor, connect the negative lead of the capacitor to ground of the arduino and the other lead of the capacitor to...
I am making a coil gun for my high school physics project and I am running into some issues.
I am using 400 turns of 36 gauge wire wrapped around a 1.25in diameter PVC pipe to propel a 1 inch diameter steel ball.
I started with a 6v battery but that didn't move the ball at all even with...
