What are Solenoids?
A solenoid is defined as a coil of wire commonly in the form of a long cylinder that when carrying a current resembles a bar magnet so that a moveable core is drawn into the coil when a current flows. A more simple definition is that a solenoid is a coil and a moveable iron core used to convert electrical energy into mechanical energy. Solenoids have been around for decades but now range in size from less than one-quarter of an inch to more than 15 inches in diameter with force outputs of less than an ounce to a ton.
