How long can an inductor store energy if it were to be suddenly

It''s definitely within a millisecond. When you abruptly disconnect an inductor from its power source it will try to rid itself of its contained energy as quickly as possible. The general rule of thumb is that the current flowing through an inductor cannot change instantly (di/dt < infinity).

Turning off (collapsing the field) of large inductors

Wait until the capacitor voltage rises to a peak and then disconnect it. The voltage can be calculated from the energy of the inductor e.g. $$ LI^2 = CV^2. $$ The fall time is determined to be half of one sine wave whose frequency is $$ f=frac{1}{2pisqrt{LC}} $$ You also get to save most of the energy for the next cycle.

Can you store energy in an inductor and use it later?

In switching voltage regulators and other energy storage apps, bigger Q is better. The best off-the-shelf inductors (all non-superconducting) at popular suppliers have a Q factor of 150 @ 25KHz. Most capacitors have an order of magnitude better energy storage (higher Q) than that. People can and do store some energy in inductors for use later.
