A ladder that has a top portion that has numerous magnets attached or embedded into it. The magnets surround the sides of the ladder top as well as attached to the underside of the top plate. In this way, tools, fasteners, paint cans, or any other metal items can be secured quickly and safely to the ladder top at any time. Moreover, because the device uses thin, flexible magnets, the ladder top is no bulkier than a normal ladder top. Finally, because of the construction, the ladder top is not covered by anything that impairs using the top in a normal way, such as sitting or standing on the top (although this is not a recommended practice, many workers routinely do this as part of their working habits). With this device, workers can fully utilize the ladder as if there was no magnetic holder attached.

I claim: 1. A ladder comprising: a) a formed head piece having a flat top, having an underside, and at least one side, extending downward from said flat top; b) a pair of support members, being oppositely disposed, each of said pair of support members having a top end, the top end of each of said p
I claim: 1. A ladder comprising: a) a formed head piece having a flat top, having an underside, and at least one side, extending downward from said flat top; b) a pair of support members, being oppositely disposed, each of said pair of support members having a top end, the top end of each of said pair of support members being pivotably attached to said formed head piece; and c) at least one magnetic strip formed of a quantity of magnetic powder and a means for encapsulating said magnetic powder into said formed headpiece. 2. The ladder of claim 1 wherein the quantity of magnetic powder is fixedly attached to said formed headpiece by means of encapsulating the at least one magnetic strip in a resinous material. 3. The ladder of claim 1 wherein the quantity of magnetic powder is fixedly attached to the underside of said flat top of said formed head piece. 4. The ladder of claim 1 wherein the quantity of magnetic powder is fixedly attached to the at least one side. 5. A magnetic ladder comprising: a) a generally rectangular headpiece, having an underside; b) four sides, attached to said generally rectangular head piece and extending vertically downward therefrom, forming a box having an open bottom; c) a pair of support members, being oppositely disposed, each of said pair of support members having a top end, the top end of each of said pair of support members being pivotable attached to said generally rectangular head piece; and d) at least one magnetic strip formed of a quantity of magnetic powder and a means for encapsulating said magnetic powder into said generally rectangular headpiece. 6. The ladder of claim 5 further comprising a second magnetic strip, fixedly attached to the underside of said generally rectangular head piece. 7. The ladder of claim 5 further comprising a plurality of magnetic strips, one of said plurality of magnetic strips being fixedly attached to each of said four sides of said box. 8. The ladder of claim 7 wherein the magnetic strips are fixedly attached to said generally rectangular head piece wherein the means of encapsulating the magnetic strips further comprises a resinous material. 9. A method of forming a magnetic top, for ladders having a head member and a pair of supports, pivotably attached to said head member, and further wherein said head member forms a mold having a plurality of formed channels therein, comprising the steps of: a) pouring a quantity of magnetic powder into each of said plurality of formed channels; and b) filling the mold with a quantity of moldable material to encapsulate the quantity of magnetic powder. 10. The method of claim 9 further comprising the steps of: a) before pouring a quantity of magnetic powder into each of said plurality of formed channels, coating the mold with a quantity of molded material, such that said quantity of magnetic powder is placed between two layers of molded material after step b is completed. 11. The method of claim 9 wherein the moldable material is selected from the group of: plastic, fiberglass, or resin.
