NathanSM said:Currently I am having an issue I do not understand. When plug the 14V battery into a length of wire with 1.6 ohms of resistance I only read 7 amps.
You have been told multiple times and several times by me
GET MUCH MORE turns = more resistance
You don't seem to listen to what you are being told
Higher voltage isn't the answer, 5V generates a nice electromagnet.
When you have only a few ohms of resistance, you are effectively short circuiting the
battery/power supply. That's why you don't read any voltage across the battery when
it is connected.
Again ...
If you are not using AWG/SWG of around 26 or finer and 500 - 1000 or more turns
you WILL NOT achieve you goal
a bobbin of 28 SWG wire as purchased roughly 2.5" long 1.5" diameter
bare the 2 ends and measure the resistance and see what it is
