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 - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o
