Why use a solenoid to engage the starter?

When low-current power from the starting battery is applied to the starter solenoid, usually through a key-operated switch, the solenoid closes high-current contacts for the starter motor and it starts to run. Once the engine starts, the key-operated switch is opened and the solenoid opens the contacts to the starter motor. All modern starters rely on the solenoid to engage the starter drive with the ring gear of the flywheel.

What causes a starter to spin without contact?

Free spinning is when, for some reason, the starter gear is just spinning without contacting anything. The sound is similar to that of a small drill spinning.
