How do inductors store energy as a magnetic field?
This is an excellent question. A good discussion can be found in Feynman''s Lectures part 2, chapter 27. See the link below. The discussion is about a capacitor storing energy in the E-field, but a similar story can be made for an inductor and the magnetic field.

Is there a voltage across an ideal inductor?
Anyway, that magnetic field stores energy. It takes energy to create the field (i.e., to ramp up the current), and the inductor returns that energy to the circuit when the field collapses (current ramping back down.) Those changes
Voltage across an inductor after flipping a switch
What is the voltage on the inductor right after the change? Relevant Equations ω=1/sqrt(LC) I(t)=-ωQsin(ωt) When the energy of the capacitor is minimal it has no charge therefore the voltage on it is 0.

Chapter 03: Electrical Transients
= 0, the voltage across the inductor is V; in an ideal inductor, current cannot change instantly, so the applied voltage appears across the inductor. At time t = ∞, voltage across the inductor is zero. The current through the ideal inductor at time t = 0, and at time t = ∞ the current through the inductor is equal to V / R.
Inductance: Energy Storage And Circuit Optimization
Inductors, electrical components that oppose the flow of current, store energy in their magnetic field. This stored energy is influenced by several factors, including the inductance of the inductor, the current flowing through it, and the magnetic field it generates. Understanding the relationship between these entities is crucial for designing and optimizing electrical circuits

Energy Stored in Inductor
Suppose I charged an inductor by connecting to a DC supply and after charging I suddenly removed the battery. So what will happen to the stored energy in the inductor. An inductor maintain its current (tightly coupled to the energy storing magnetic field) as long as it can. In that, a long spark may result (as the voltage on the terminals
What happens if we suddenly open the switch in
Let''s say we have an LC oscillating circuit with a switch in the circuit (that doesn''t have any resistance), I wanted to understand what will happen if we suddenly open the switch. Since inductor current changes rapidly in the circuit,
Inductors
There is no source to the right of the switch and there is a resistor connected to the inductor, so the resistor consumes electric energy stored in the inductor and converts it into heat while no energy is being added to the inductor. After a long transition time, the current through the inductor will approach zero, as shown in Fig. 15.3.
Inductive energy storage suddenly disconnects

B 3 through loop iii, and the capacitor charges the inductor through loop iv. Because the capacitor voltage cannot change suddenly, the capacitor will continue to charge the inductor after
The energy stored in an inductor
So now the inductor slowly build up its magnetic field until the current flow reaches maximum value. Then suddenly, you take away the inductor (completely isolating it, i.e. the two terminals not connect with anything), put it at somewhere else, keep it like that for some duration (few seconds, minutes, hours, days, etc). But it is a
Discharging an inductor
In this circuit we apply a positive voltage at V1 greater than the output. This causes the current in the inductor to increase, ramping up. When V1 disappears or goes

"Why" Does inductive Kickback Happen? | All About Circuits
The voltage across an inductor is related to the change in current, and the voltage direction is such that it tends to oppose the change of current; this is because the change in current is storing energy in the magnetic field of the inductor.
What happens to the current when an inductor is suddenly
When an inductor is suddenly disconnected, the current cannot immediately drop to zero because the inductor resists sudden changes in current. Specifically: Current Cannot Change Instantly. Reason: The inductor stores magnetic field energy, and when the current
Inductive energy storage suddenly disconnects
Energy Storage Inductor . The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor. a mechanical clutch is required

Discharging an inductor
Lets consider storing Energy in both a capacitor and an inductor. However, the problem with storing energy in a inductor is that the current has to be kept circulating. Our current technology makes that quite lossy for long

Basic Facts about Inductors [Lesson 1] Overview of inductors
An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction.
6 FAQs about [The inductor suddenly disconnects after storing energy]
How do inductors store energy?
I know inductors store energy in their magnetic field, generated by current flowing through them. What if you wired an inductor in series with a power source, load, and switch and allowed the current to freely flow. Now suddenly you open the switch, what happens?
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:
What happens if you disconnect an inductor?
Thus, when you disconnect the inductor, the current changes from whatever it was to 0 in a very short amount of time. The resulting di dt d i d t becomes very large making the induced voltage very large. The formula has a - in front of it to indicate that it's in the opposite direction.It is a minor matter however.
What happens if an inductor is suddenly open circuited?
Physics Stack Exchange What happens when the circuit for an inductor is suddenly open circuited? A current through an inductor cannot change abruptly, so what happens if I have an inductor with current passing through, and I suddenly open circuit it so that no current flows through? You get an arc (hence the diodes protecting solenoids).
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 happens if a current passes through an inductor?
A current through an inductor cannot change abruptly, so what happens if I have an inductor with current passing through, and I suddenly open circuit it so that no current flows through? You get an arc (hence the diodes protecting solenoids). I believe the circuit technically explodes in this case. di t dt v ( t) = L
