Solenoids<^< Stepper Motors | Course Index | Adding Drivers >^> A handy electromechanical device for giving something a nudge.  It consists of an electromagnet with a moveable magnetic plunger down the middle. When a current flows through the electromagnet coil, it becomes magnetised and pulls the plunger into the centre of the coil.  Like the motor, the solenoid requires a high current, and so a driver circuit is needed. There is a risk of a high voltage generated when the solenoid switches off and the magnetic field collapses. Again, a diode should be used to protect the electronic components. <^< Stepper Motors | Course index | Adding Drivers >^> |
