The solenoid's purpose is two-fold.. To bridge the contacts between the battery cable and starter field windings. The second function is to move the bendix along the starter shaft until it engages the flywheel. If the starter is spinning, the solenoid is doing its job.
Without actually hearing the noise, I'm thinking the starter bendix is going out, allowing the starter to "freewheel"..
