Why will a stuck solenoid draw excessive amps?
 
Why will a solenoid with a stuck plunger draw excessive
amps? I am familiar with resistance and inductive reactance.

Obviously, there must be less inductive reactance, but why?

How does the location of a solenoid plunger effect its
current draw or the amount of inductive reactance present?

Where is the majority of the "soft iron mass" located, when the
solenoid is extended? Where it is close to every turn of wire,
or only close to a few? Think about what it means to have
reduced iron mass exposed to the same flux.
