ABSTRACT:
Methods and devices for securing the bottom of 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 vitroceramic or smooth-top stove top, or other component of the cook top in close proximity to the bottom of the cookware when it is on the cooking surface. The magnetic source prevents the cookware from being accidentally knocked off the cook top.
