Science, bitches!
There seem to be a lot of confusion about how microcoils (or contact coils, as they should really be called) actually work. I'm a physicist in graduate school, so let me give you my perspective.
Physics states that electrons always follow the path that dissipates the least energy. This the shortest circuit, and thus conventional coil knowledge would tell you that your device would short circuit if the coils were all touching. This actually does happen, but only for the first microsecond. After that, the current causes local heating along the path of the short circuit, and metal's resistance increases as it heats up The effect is quantum mechanical, but here is a simple 'what happens'
http://www.allaboutcircuits.com/vol_1/chpt_12/6.htmlThis is where physics fights for us. As the resistance increases, suddenly the path that dissipates the least energy is not the shortest one. The high temperatures involved make the current constantly seek the coolest part of the coil, and this produces even heating.
What makes microcoils more temperamental is the fact that the contact must be flush, and even, or hotspots will murder your coil. Ideally only the temperature would govern our coil's resistance. There is a trick to get fantastic contact where you dry fire the coil on the battery, and then press tightly with pliers while its still hot. Originally seen, 3:38

If you made it this far, THANKS FOR READING, I LOVE YOU! Microcoils are cool; I need some smaller objects to wrap them with!
