Magnet wire is super useful stuff, and when you need it there’s nothing else that will work. Whether you’re winding a transformer or choke, fashioning your own motors or just playing with electromagnetism in general, nothing beats this thin-gauge enameled wire. This kit comes with three common gauges of wire: 22, 26 and 30AWG. Everyone has his or her own method for removing the enamel insulation and make a connection to this stuff, but a little abrasion with some sandpaper or scraping with a hobby knife works well. If you have an open flame handy, you can burn the enamel off as well, just be careful! Learn More

Silicone-sheathing wire is super-flexible and soft, and its also strong! Able to handle up to 200°C and up to 600V, it will do when PVC covered wire wimps out. Adafruit like this wire for being extremely supple and flexible, so it is great for wearables or projects where the wire-harness has to be able to deal with a lot of bending. Learn More
