We theoretically study a magnon-polariton (MP), quantum hybrid state of magnetization dynamics and microwave, in a dynamical inductor which consists of a coil involving a magnetic insulator. Based on the standard microwave transmission theory, we demonstrate ultrastrong coupled MPs at room temperature in an RLC-circuit with the dynamical inductor. Also, we discuss a possibility to realize deep-strong coupled MPs by revealing the relation between the coupling strength and size of the dynamical inductor.
