I want to make a electromagnet. I wound up 30AWG magnet wire around thick Iron core and when i connected it to my power supply, 16V 3A, It got HOT very quickly. Should i have more coils? will that help decrease heat? And for the battery, it will drain an normal AA battery pretty quick right?
And recently, i took apart my old broken hard drive and i found a stepping motor. How do i make it work? Where can i find the datasheet? I tried connecting it to DC and AC. It just makes a click and stops and shorts
