Use a DMM in ohms mode to check continuity.
If it is a field coil type you could tap into a 250-450V radio B+ to power the field (put a 150mA dial lamp in series with it to act as a fuse), and then drive the voice coil with the radio's speaker connections.

I appreciate the response. It appears to have a coil on back the speaker and under it.maybe in parallel along with voice coil...not normally what I have seen before with electro magnets.this thing is quite bulky .
