The energy storage coil suddenly breaks

What happens when a coil is fully charged?

As the current of the superconducting coil (which is a pure inductance) increases, the magnetic field also increases and all electrical energy is stored in the magnetic field. Once the critical current (Ic) is reached, the voltage across the coil terminals is reduced to zero. At this stage, the system is fully charged, and the energy can be stored as long as desired.

What are superconducting magnetic energy storage coils?

Superconducting magnetic energy storage (SMES) coils, also known as superconducting inductor coils, are used to store electrical energy in the magnetic field of a large coil for later use. Their main purpose is to supply large, repetitive power pulses and for load leveling applications.

What are superconducting inductive coils?

Superconducting Inductive Coils, also known as Superconducting Magnetic Energy Storage (SMES) coils, combine superconductivity and magnetic energy storage concepts to store electrical energy.

Can a superconducting coil be connected to a constant DC power supply?

A superconducting coil can be connected to a constant DC power supply as shown in Figure 7.8. When the current of the coil, which is a pure inductance, increases, the magnetic field also increases and all electrical energy is stored in the magnetic field. Once the critical current (Ic) is reached, the voltage across the coil terminals is reduced to zero.

Why does a coil store no energy?

This is not an equilibrium configuration and then, since the electrons in the metal are free to move, the charges redistribute in the wire, nullifying the potential difference. Now the coil stores no energy. So where did the energy go?

Are superconducting coils better than resistive coils?

Superconducting coils are more energy-efficient than resistive coils, as they dramatically reduce the energy needed to generate a magnetic field. Additional power from external sources is scarcely required to maintain current in such coils for a lengthy period of time.
