Methods include:\n\n* Direct induction, (most common, widely used for electric kettles and for charging electric toothbrushes)\n* Resonant magnetic induction\n* Electrical conduction via contact points\n* Electromagnetic radiation in the form of microwaves or lasers\n\n== Instructions ==\n\nDisclaimer: Take appropriate precautions, particularly if there is exposure strong electromagnetic fields.
