DC Motors: The Basics – ITP Physical Computing

WebAn electromagnet uses an electrical current to generate a magnetic field. There are three ways to strengthen an electromagnet: increasing current. increasing the number of turns … WebA motor works on the same principles, but in the opposite direction -- it converts electrical energy into mechanical energy. To do this, a motor needs a special kind of magnet known as an electromagnet. In its simplest form, this consists of an iron bar wrapped in a coil of wire. If you pass an electric current through the wire, a magnetic ... WebIntroduction. Self-contained devices that convert electrical, chemical, or nuclear energy into mechanical energy are called motors and engines. In many areas of the world they have replaced human and animal power by providing energy for transportation and for driving all kinds of machines. The chemical energy of a fuel can be converted by ... how to give nested css
