It is a little mysterious to the naked eye, Dave. pete 23's description of its operation is better than what I'd have come up with. The naked eye part comes in as part of what makes the gear on the motor move into the teeth on the ring gear. She shaft is machined with a slight helix to it. It is not round as it may appear to the eye. When you first put juice to the starter motor, it is spinning at a very high rate and the gear rides that helix (think of the loosest, most wobbly thread fit you can imagine) until it engages with the ring gear. And, again just as Pete described, the running motor will speed up the shaft on the starter motor to faster than it is being driven by electricity, and the gear will back off. There is typically a very light spring that will hold the gear back that will speed its pulling back and prevent the starter gear from vibrating out and getting into the ring gear while you are running.
A solenoid has taken different configurations over the years, but you can think of it as an electrically operated actuator that forces the starter gear into the ring gear. It operates only when the switch is held in the start mode. On a modern car, when it's working right, the starter motor operates only when you hold the key in the start position. That position powers the solenoid which, with electrical power, moves the starter gear into the ring gear. When your motor starts and you let the key switch fall back to the run position, it cuts off power not only to the starter motor but to the solenoid, which then allows the starter gear to return to its rest position.

Today's Featured Article - Talk of the Town: Winterizing Engines - To Drain or Not to Drain? - by Russ Berry. What is this strange attraction I have to equipment and machinery? How did I get this way? I came from the suburbs and own a small horse farm in rural Loudoun County, Virginia. You can call me a "weekend farmer." The local farmers do. Does it bother me? No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
