They probably wouldn't state the inductance.
One outfit that makes utility transformer test sets say that their
gadgets measure up to 10H. I was hoping to find something outrageous.
Hammond makes a 200H inductor. It is NOT good for 30 amps!

The superconducting magnets used in MRI machines have a very high
inductance. I have seen values between 50 and 100H quoted.
