Unless I'm mistaken, it sounds like you're expressing interest in using a magnet as a form for an electromagnet? Strength depends on which way the electric current (which induces a magnetic field) is flowing in relation to the permanent magnet poles.
With DC one way will work with the magnet, the other way will work against the magnet, with AC you run the risk of demagnetizing the magnet to a degree determined by field strength.
I'd do away with magnets at the winding and just use steel threaded stock allowing ease of mounting, wind it up like an electro magnet and then drive that like a (low power) speaker (the permanent magnet can be like a slug that moves).
Generally speaking, you'll want some stuff to move and some stuff to remain still for stuff like this to work. Have fun!

It will be a static system.
If your goal is to create vibration, you will need something to excite the spring. Physically reaching over and jostling it will work, until equilibrium (rest) is reached, for drone you'll want something active. Like an alternating magnetic field (the mechanics behind a speaker) or a periodic on/off switching of your battery.
I'd say: by all means, build the thing, and then modify it to function if it does not meet your needs. It's the best way to learn this shit. Take a breath and dive in. Have fun!

I'm saddened that RadioShack is shutting most of it down, honestly. I mean I love buying stuff off e-bay as much as the next guy and/or Thailand via Tayda, but radioshack was just cool for some spur of the moment needs.. I bought all their bigass 20 watt 8 ohm resistors for like 97 cents when the one here went under. I figured I may make a speaker load simulator for testing tube amps..
I had a basic idea for a controllable spring exciter.. You could use a small electric motor with an off-center (unbalanced) item on the end, so when you spin it, it will vibrate, and it will vibrate more and more as the motor spins faster. Kind of like the old rock polishers, minus the smoothing media in a can! :P A rotary vibrator? mmm.. anyway. Simple solid state motor speed control via a potentiometer controlling voltage.. boom.
