• Simple calculations lead to a conclusion that there is an upper bound to the frequency at which magnetic refrigerators can operate, f max ∼ 2 × 10 2 Hz . The principal factor limiting the operation frequency is a trade-off between thermal conductivity and viscous friction. The main events take place inside the magnetocaloric bed-the fundamental unit of any magnetic refrigerator-largely independently from the rest of the apparatus.
