Spring Reverb Driver Idea - Query

Hey! I have a driver idea for a custom spring reverb build. Omitting that the devil is in the detail I'll keep it as simple as possible.

A speaker output connected to a toroidal inductor with a ferrite core suspended in the center:

Would this drive the spring? Ideally the ferrite core should be radially magnetised, but those aren't readily available.

Advice would be highly appreciated.
