Methods and devices for securing an item of cookware to the burner of a stove top by use of magnetism. The magnet(s) may be permanent magnets or electromagnets. The cookware may comprise a permanent magnet disposed on or in the base of the cookware. The burner comprises a magnetic material such as steel or iron. The magnetic material may be in the grate of the cook top, in the electric coil of an electric burner, in the surface of a smooth-top stove top, or any other component of the cook top which is in close proximity to the bottom of the cookware when it is placed on the cooking surface. When the cookware is placed on the stove top, the magnetic field of the permanent magnet creates a force on the magnetic material biasing the cookware against the stove top and securing the cookware to the cook top.

1. An item of cookware for use on a cooking stove having a cooking surface, comprising: a base comprising a bottom outer surface and a cooking surface on a top side of the base and a bottom outer surface on the bottom side of the base; andan electromagnetic disposed on or in the base, the electromagnetic being adjustable to turn the electromagnet on or off, wherein when the electromagnetic is turned on, the electromagnet produces a magnetic field which is strong enough to hold the cookware against the cooking surface with sufficient force to prevent the cookware from being accidentally bumped off the cooking surface. 2. The cookware of claim 1, wherein the electromagnet is adjustable to adjust the strength of the magnetic field to magnitudes between fully on and fully off. 3. The cookware of claim 1, wherein the electromagnet is disposed between the cooking surface and the bottom outside surface of the base. 4. The cookware of claim 1, wherein the cookware is one of a pot, pan or bowl. 5. The cookware of claim 1, wherein the cookware is constructed of one of stainless steel, glass, tempered glass, aluminum. 6. The cookware of claim 2, wherein the cookware is constructed of one of stainless steel, glass, tempered glass, aluminum. 7. The cookware of claim 2, wherein the cookware is constructed of one of stainless steel, glass, tempered glass, aluminum. 8. A cooking stove, comprising: a cook top having at least one heating station;said heating station comprising a heating element and a heating surface over said heating element for placing an item of cookware thereon; anda magnetic field source disposed in said cook top for creating a magnetic field to create a force tending to bias an item of cookware against said heating surface, said magnetic field source being adjustable such that the strength of the magnetic field at the heating surface may be adjusted to vary said strength and not merely turn the magnetic field on and off. 9. The cooking stove of claim 8 wherein said magnetic field source is a permanent magnet. 10. The cooking stove of claim 8 wherein said magnetic field source is an electromagnet. 11. The cooking stove of claim 8 wherein the adjustability comprises moving the magnetic field source relative to said cooking surface. 12. The cooking stove of claim 8, wherein said heating element is a gas burner. 13. The cooking stove of claim 8, wherein said heating element is an electric burner.
