    Why does the impedance of inductor change with frequency?

    I understand the behavior of inductor but i just puzzle what is opposing to the change of current in high frequency. Originally, I guess it is because there are more energy stored in form of magnetic field in high frequency range. But the formual just says the opposite. The energy remains the...

    Why does the impedance of inductor change with frequency?

    The power stored in an inductor is E=0.5LI2 which is independent of frequency However, the impedance is ωL. So, what makes the impedance increase with frequency?
