Can Inductors Discharge Their Stored Energy?

[chahya]

inductor can discharge or not?

 

[zhermes]

Yes, and inductor can discharge.

Well, at least in English, the term "charge" refers to electric charge storage, or electrical potential energy storage (like in a battery). So you would charge and discharge a capacitor or battery, for example.

The energy stored in an inductor is magnetic in nature, so the terms charge and discharge would not normally be used, I believe. I'm not sure what alternate term might be used with an inductor, as you store and release the magnetic energy...

Hey Berke,
When I was a kid, I used to put batteries to most anything. I tried tried it on a flourescent ballast I had salvaged. It "felt" like it discharged ><

That made me chuckle a little Mike...

Superconducting magnets used in MRI's are essentially large zero-resistance inductances running in persistent mode (large dc current, shorted coil). Even though they have a large inductance, the L/R time constant is extremely long. These inductances can be discharged into external resistances under controlled conditions. Sometimes the magnet coil can absorb its own stored energy under certain self-discharge modes.
