For winding custom coils, or very fine-pitch rework, Adafruit always reach for magnet wire. Magnet wire is very very thin (0.1mm diameter!) copper wire with a very thin...

Solenoids are basically electromagnets: they are made of a coil of copper wire with an armature (a slug of metal) in the middle. When the coil is energized, the...

When you want to measure AC current it is impractical and hazardous to cut in to your live wiring. The analog AC current sensor developed by DFRobot is a good solution to this problem. Using induction you can measure AC current without intrusive methods. Place your AC wire inside the unit, connect the unit to the sensor board using the 3.5mm jack connector and connect the sensor board to an analog input on your microcontroller. Use this sensor to measure AC motors, lighting equipment, air compressors or any other devices that use AC current.

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!

This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.
