Hence, the magnetocaloric effect is simply a mechanism for changing the temperature of a substance up and down by the use of an external magnetic field. An example of an ADR cycle is shown in the figure below. The temperature regime shown corresponds to test parameters during the design of the fridge. Steps 1-4 form a closed cycle. Thus, the heat engine returns to its initial state.
Question Explain the terms adiabatic and isothermal.
Look at the ADR cycle. The ADR is a physical realization of the abstract textbook heat engine. Summary The ADR manages to move heat from the cold detector to the warm heat bath by having its own temperature cycled. In fact, Dr. Shirron's group is currently working on solving this problem.
