The inexpensive "universal testers" that sell for less than $25 on Ebay will evaluate most toroid cores for inductance. Just add 5, 10 , and 20 turns, measure inductance, then do rhe math to reveal probable characterestics. Not super accurate, but should get you in the ballpark. Further tests can be done to find core saturation, heat rise, and q-factor. All this does require some knowledge of electronics and maybe a little physics.
