If I wanted a constant B field using an element

[Kidphysics]

Or some naturally occurring material what would I use. I'd like the strongest constant uniform magnetic field possible. Is there some sheet of material I can use?

Naturally occurring materials do not have strong or uniform magnetic fields. There are cheap, powerful, and uniform magnets available commercially, but they use special alloys and techniques to magnetize those elements.

interesting, thanks; do you recommenced a place?

I don't want to recommend a specific manufacturer (and I don't know them anyway), search engines should give you a long list of them. Neodymium magnets are the most common type.

There are a few options for creating a constant and strong magnetic field using an element or naturally occurring material. One option is to use a permanent magnet, such as a neodymium magnet, which can produce a strong and constant magnetic field. Another option is to use a ferromagnetic material, such as iron or nickel, which can be magnetized to create a constant and strong magnetic field. However, these materials may not be suitable for creating a uniform magnetic field, as their strength can vary across different areas.

If you are looking for a sheet of material that can produce a constant and uniform magnetic field, you may want to consider using a superconducting material. Superconductors, when cooled to very low temperatures, can produce a strong and uniform magnetic field that is constant. However, these materials require specialized equipment and techniques for cooling and handling, making them more difficult to work with.

Another option is to use a Helmholtz coil, which is a set of two circular coils placed parallel to each other and connected in series. When a current is passed through these coils, they can produce a uniform and constant magnetic field between them. This method is commonly used in laboratory settings for creating precise and controlled magnetic fields.

Ultimately, the best material to use for creating a constant and strong magnetic field will depend on the specific requirements of your experiment or application. It is important to carefully consider the properties and limitations of different materials before making a decision.
