Discuss application of thermodynamic principles to magnetic

Solution

Superconducting magnetic systems store an electrical input in the magnetic field
created by flow of electric current in a coil of cryogenically cooled, superconducting
material. This storage type provides power nearly instantaneously, and with very low
input-to-output loss of electricity. Superconducting magnetic systems are used by
high-speed magnetic-levitation trains, by utilities for power-quality control, and by
industry for special applications such as microchip fabrication.

Flywheels provide another way to store an electrical input—as kinetic energy.
When electricity is required, kinetic energy is drained from the spinning flywheel and
provided to a generator. Flywheels typically exhibit low input-to-output loss of electricity.
Flywheel storage is used, for instance, by Internet providers to protect equipment
from power outages
