Hi fellows,

I'am going to make an electromagnet.But first everything must be clear.

My power supply 24v and 2 amp max.Thus i want my electromagnet work at 1.5 amps at max.

24v/1.5amp =16 ohms.Awg 18 is 1mm diameter wire and it's max amperage is 2.3 amps.

For 16 ohms i will buy 763 meters of it.

My core is 50mm diameter and length is 50mm.Now i have to calculate how many turns **approximately**.And here we go;

i Have to do this with layer to layer because of each layer radius is going bigger. So how can we do that?
