Abstract

An aerosol-forming article for use in an electrically heated aerosol-generating device is provided, the aerosol-forming article including a mouthpiece, an aerosol-forming substrate, and a plurality of magnetic particles including a magnetic material having a Curie temperature of between 60 degrees Celsius and 200 degrees Celsius. An electrically heated aerosol-generating device for receiving the aerosol-forming article is also provided, the device including a heater element configured to heat the aerosol-forming article, an inductor, and a controller configured to measure an inductance of the inductor and to control a supply of electrical current to the heater element in response to the measured inductance.

First claim

1 . An aerosol-forming article for an electrically heated aerosol-generating device, the aerosol-forming article comprising:
a mouthpiece; an aerosol-forming substrate disposed in co-axial alignment with the mouthpiece; and a plurality of magnetic particles comprising a magnetic material having a Curie temperature of between about 60 degrees Celsius and about 200 degrees Celsius.

2 . The aerosol-forming article according to claim 1 , wherein the plurality of magnetic particles are disposed within the aerosol-forming substrate.

3 . The aerosol-forming article according to claim 1 , wherein the plurality of magnetic particles are present in an amount of between about 1 percent by weight and about 30 percent by weight of the aerosol-forming substrate.

4 . The aerosol-forming article according to claim 1 , wherein an average diameter of the magnetic particles is between about 25 micrometers and about 75 micrometers.
