6 FAQs about [Magnetic loose energy storage]
What is superconducting magnetic energy storage (SMES)?
Superconducting magnetic energy storage (SMES) systems store energy in the magnetic field created by the flow of direct current in a superconducting coil that has been cryogenically cooled to a temperature below its superconducting critical temperature. This use of superconducting coils to store magnetic energy was invented by M. Ferrier in 1970.
Are magnetic device energy storage distribution relations constant?

How does air gap affect magnetic energy storage?
Compare the magnetic core energy storage expression (9) with the total energy storage expression (14), it can be seen that the total energy increases by z-multiple after the addition of air gap, from Eqs. (16), (17) indicate almost all the energy is stored in the air gap, and the energy of magnetic devices expands and increases.
Does the storage energy distribution ratio of magnetic devices change after air gap?
The innovation point of this paper is to analyze storage energy distribution ratio on the core and gap of magnetic devices from the perspective of energy that the storage energy distribution ratio of magnetic devices is changed after the addition of air gap.
When was superconducting magnetic energy storage invented?
Ferrier first unveiled the superconducting magnetic energy storage device in 1969 as a source of power to meet the varying power requirements throughout the day. Germany developed the first utility-scale CAES plant in the world in 1978, with a 290 MW capacity.
How much energy is stored in a magnetic core?
Compare equations (36), (37), that the energy stored in the magnetic core is only 3.03% of the total energy, and the ratio of the energy stored in the magnetic core to the energy stored in the air gap is 1:32. It is verified that most energy is stored in the air gap during energy conversion of magnetic devices.
