For a solenoid...When the outer coil (with core) was used as the primary coil, why is the voltage stepped down a different amount than it was stepped up when the inner core was the primary??

If you reverse the process, say, take the secondary coil and reverse the order with the primary coil, the the voltage should be stepped down more due to the resistance of the electrical wire through which the current is flowing. Current flow should be regarded as an "uphill" journey, encountering natural resistance of the wire it is flowing through. This current can build momentum, of course, so if you start with the secondary coil, which has more windings, the current will build momentum and result in a lower voltage than was proportionally the case when you had the two windings in their proper order. A solenoid, by the way, is a tightly wrapped helix of electrical wire that is wrapped around a ferromagnetic core. These may be paired together to produce step-up transformers or step-down transformers. There are lots of varieties of transformers, but they all operate by this basic principle.
