Hey there guys, Paul here, from theengineeringmindset.com. In this video we're going to be looking more into solenoids and how they work. We're going to look at permanent magnets and how to see their magnetic field. We're going to create an electric magnet from a wire. We're going to be looking at some real-world solenoids, and we'll also cut one open using some power tools. And finally, we're going to learn how to build our own basic solenoid. If you are working with solenoid valves, you're going to want to download the magnetic tool app from Danfoss, who have kindly sponsored this video. The app makes it easy to test that your solenoid valve is working properly and works with both AC and DC versions. You can download it for free, for Android and iPhone, using the link in the video description below. So we'll start off, by taking a look at a standard bar magnet. This is a permanent mag
