Imagine a spool of 20AWG copper wire. The inner diameter of the spool is 4 inches. The outer diameter of the coiled wire is 5 inches. The coil is only an inch tall, so it is a short spool, but it is packed pretty densely with windings. There is no cooling system as of yet. I just want to know if...
Suppose I have a current carrying wire that is 20 AWG copper. There is insulation on the copper wire that is rated for 200 degrees C. I have 500 meters of the wire wound into a coil. The coil takes up a total volume of 0.0001157 meters cubed (roughly 1000 turns). Suppose I run 3 amps of current...
