We propose an externally controllable analogue black hole independent of the system parameters by using a hybrid system of a one-dimensional chain of single-domain nanomagnets and a superconducting quantum circuit. It is clarified that a tunable analogue black hole is created by applying a magnetic flux soliton generated in a one-dimensional chain of single-domain nanomagnets to a superconducting quantum circuit as a spatially changing external magnetic field. It is also shown that Hawking radiation in our system is observable.
