Abstract

An electromagnetic appliance for stovetop cookware comprising an electromagnetic plate-like appliance position able on a stove surface element having a switch for generating a magnetic field so that when paramagnetic cookware is placed on the electromagnetic plate-like appliance and the electromagnet is energized, the superjacent cooking ware will be magnetically prevented from accidental movement of the cookware without de-energizing the electromagnet.

Claims

1. An electromagnetic appliance for holding paramagnetic cookware to a stove appliances having at least one plug-in burner element comprising:

An electromagnetic housing comprising a paramagnetic top surface, a paramagnetic bottom surface, and an outer wall joining said top and bottom surfaces forming an enclosed compartment;

said housing adapted to be placed on a paramagnetic burner element and to support said paramagnetic cookware on said to surface of said housing;

a power source connected to said housing;

an electromagnet fully contained and enclosed within said housing in electrical communication with said power source for providing a magnetic field projecting from both said to and bottom surfaces, said electromagnet extending throughout all of said enclosed compartment for providing a continuous magnetic field over all of said top and bottom surfaces; and

a switch for activating and de-activating the electromagnet whereby when activated a magnetic field is generated holding the electromagnetic cookware to the burner element.

2. The electromagnetic appliance of claim 1, wherein said electromagnetic appliance housing, comprises:

a top planar surface and a bottom planar surface having a peripheral wall therebetween forming compartment housing said electromagnet;

a power cord extending from said electromagnet through said handle to a power source; and

a switch within said handle for activating and deactivating the electromagnet.

3. The electromagnetic appliance of claim 2, wherein said electromagnetic, appliance handle further provides an on/off state visual indicator.

4. The electromagnetic appliance of claim 3, wherein said power source is an AC power source.

5. The electromagnetic, appliance of claim 3, wherein said power source is a DC power source.

6. An electromagnetic appliance for holding paramagnetic cookware to a stove appliance having a crate of paramagnetic material positioned over a heating element comprising:

An electromagnetic housing comprising a planar paramagnetic to surface, a planar paramagnetic bottom surface, and an outer wall joining said top and bottom surfaces forming an enclosed compartment;

said housing adapted to be placed on said grate and to support said paramagnetic cookware on said top surface of said housing;

a power source connected to said housing;

an electromagnet fully contained and enclosed within said housing in electrical communication with said power source for providing a magnetic field, projecting from both said top and bottom surfaces, said electromagnet extending throughout all of said enclosed compartment for providing a continuous magnetic field over all of said top and bottom surfaces; and

a switch for activating and de-activating the electromagnet whereby when activated a magnetic field is generated holding the electromagnetic cookware to the grate.

7. A method of securing a cookware of electromagnetic material to a burner of paramagnetic material or a grate of paramagnetic material over a source of heat consisting of the steps of:

placing an electromagnetic housing comprising a planar paramagnetic top surface, a planar paramagnetic bottom surface, and an outer wall joining said top and bottom surfaces forming an enclosed compartment on said burner or grate, an electromagnet fully contained and enclosed within said housing in electrical communication with an external power source for generating a magnetic field projecting from both said top and bottom surfaces of said housing, said electromagnet extending throughout all of said enclosed compartment for providing a continuous magnetic field over all of said top and bottom surfaces;

placing said cookware on said top surface of said housing; and

using a switch connected to said power source for activating and de-activating the electromagnet whereby when activated a magnetic field is generated holding the electromagnetic cookware to the burner or grate and resisting movement of said cookware during use.
