How to find inductance of an unknown inductor?
I have some inductors harvested from an old power supply.They don't have an induction rating and I want to measure them.How do I do this?

Google "measuring inductance." After that, Google "finding information."

Drive it from a VFO, in series with a load resistor, and using a scope, measure the voltage across the resistor and the inductor. When the two are equal, the impedance of the inductor is the same as the resistance of the resistor. Now, since Z=wL, and you know w and Z you can find L.
This procedure won't find the current handling capability of the inductor however.

Hi, try this calculator:

(Note that I did pretty much what kelseymh suggested, but having done this before I used better search terms)

I'm impressed that you haven't gotten tired of giving the man a fish every day ;-)
Well Derin should know better, but usually it's not the same man every day. L
