Energy Stored In an Inductor - Magnetic Field Energy Density

This physics video tutorial explains how to calculate the energy stored in an inductor. It also explains how to calculate the energy density of the magnetic field created by the inductor. As the current increases, the inductor stores energy by the expansion of a magnetic field. As the current in the circuit decreases, the inductor releases energy back into the circuit as the magnetic field collapses. This video contains a few examples and practice problems.

KEEP GOING SIR

Tqsm sir!

Nicely Explaination .

[@gonzalomorenoandonaegui2052]

The Organic Chemistry Tutor forgive me for my ignorance but Why nobody is talking about EMFs as an energy storage method for vehicles and for the grid ? Could energy be stored in form of magnetic fields with superconducting coils in the future ? Or is this idea impractical ? Could exist a magnetic field that doesnt lose energy through LC ocilations ?

[@yaradiab9222]

Can I calculate the energy stored in a coil without having the current?

[@iuliancojocaru4125]

Let's say that we have an inductor of 2000 henry and we pass 31.6 amps through it, that should give us around 1 million joules or around 270 watthours, now let's say we have the same scenario but the inductor is made out of a super conducting material like YBCO below it's critical temperature and we short the inductor forming a loop. Does that mean we have stored energy like a battery?

µ0 (permeability of free space) has a constant value... µ0 = 4π × 10^-7 T m/A
