Hi all, I'm currently doing some work trying to optimize coils (basically a large center hole solenoid) for a series of experiments. Two of the variables I'm going to be able to adjust are wire gauge of the coil and amperage through the coil. Online, I have found 'rule of thumb' amperage limits for continuous use vs. wire gauge. The tests I will be running will not be running for long periods of time (maybe 10-15 minutes tops), and the amperage limits I've looked up online seem to be very limiting. I'm wondering if anyone knows where I could find equations or rules-of-thumb for short duration loads vs. wire gauge. We're probably going to have to do some failure tests to be sure, but I'd like to get close before we start winding the coils up (which will be a relatively lengthy process).
