A system displaying a hysterisis loop such as a ferromagnet, is a device for storing memory?' Explain the meaning of this statement.

Explanation

Magnetization of a ferromagnet depends on the field and also on the history of magnetization, i.e. the number of cycles of magnetization that it has been subjected to. We can say that the history of magnetization is a record or .memory. of its cycles of magnetization. If information bits are corresponding to these cycles, the system displaying such a hysteresis loop can be used as a device for storing information.
