1. A method for the synthesis of graphene or other carbon nanomaterials on a ferromagnetic substrate in an ambient atmosphere, the method comprising the steps of:
1) Introducing a ferromagnetic substrate into a closed chamber having an ambient atmosphere;
2) Applying a carbon precursor to said substrate;
3) heating the substrate by electromagnetic induction, whereby the carbon precursor is evaporated and/or thermally decomposed;
4) igniting the carbon precursor; and
5) cooling the substrate.
