How does an inductor work?
For some milliseconds the current continues to flow across the already opened switch, passing through the ionized air of the spark. The energy stored in the inductor is dissipated in this spark. Summary: An inductor doesn't "want" the current to be interrupted and therefore induces a voltage high enough to make the current continuing.
What if an inductor is connected to a source?
Suppose an inductor is connected to a source and then the source is disconnected. The inductor will have energy stored in the form of magnetic field. But there is no way/path to discharge this energy? Short answer: It will find a way/path to discharge this energy. Longer answer:
Why do inductors have a magnetic field?
However to emphasize that the magnetic field just has energy: if your inductor is made out of a perfect conductor and you disconnected it from the rest of the circuit and connected it to itself then it would maintain its current and hence the magnetic field.
What happens when a voltage is applied across an inductor?
This energy is borrowed from the power source, stored in the field, and then returned to the circuit afterwards. You can watch this process happening. When a voltage is applied across an inductor, the current rises steadily instead of jumping up at once to its final value.
What happens if you put a diode across an inductor?
In real world situations you will usually see some or all of spark, insulation break down, resistive dissipation, electromagnetic radiation and resonance. Where circuit topography allows it is common to add a diode across the inductor to allow the current to 'circulate' and dissipate energy in the winding resistance.
Can a short circuit dissipate power?
(And before you say "through the short circuit", I remind you that a short circuit has no resistance, and therefore cannot dissipate power) Suppose an inductor is connected to a source and then the source is disconnected. The inductor will have energy stored in the form of magnetic field.
How long would an inductor hold its energy if
You don't want to leave one end of a charged inductor open, that's how spark plugs in a combustion engine generate the spark to ignite the fuel. Look
What happens to an inductor if the stored energy
The energy stored in the inductor is dissipated in this spark. Summary: An inductor doesn't "want" the current to be interrupted and
Energy storage in inductors
What Is An inductor?What Is A Magnetic field?Magnetic FieldsEnergy in Magnetic FieldsEnergy Storage in An InductorLenz's law says that, if you try to start current flowing in a wire, the current will set up a magnetic field that opposes the growth of current. The universe doesn't like being disturbed, and will try to stop you. It will take more energy than you expect to get the current flowing. This additional energy isn't lost - it is stored, in the magnetic 在johnhearfield.com上查看更多信息

How long can an inductor store energy if it were to be suddenly
It's definitely within a millisecond. When you abruptly disconnect an inductor from its power source it will try to rid itself of its contained energy as quickly as possible. The general rule of thumb is
