Abstract
An assembly for evaporating a volatile material is described, the assembly comprising a device and a refill which are detachable from one another: wherein the device comprises a magnetic induction coil configured to operate with an alternating current passed therethrough at a frequency of between substantially 20 KHz to substantially 500 KHz; and wherein the refill comprises at least one magnetic susceptor having a coercivity of substantially 50 ampere/meter (H) to substantially 1500 ampere/meter (H) and a substantially liquid-tight sealed reservoir containing the volatile material; wherein, in use, the magnetic susceptor(s) is arranged to heat the material predominately by magnetic hysteresis when the magnetic susceptor(s) is at least partially positioned in the induced magnetic field generated, in use, when said alternating current is passed through the induction coil. Refills, devices and methods of use are also described.
