As a subject matter expert in comic book lore, particularly the Marvel Universe, I can provide an informed answer to your question about Magneto's abilities. Magneto, also known as Erik Lehnsherr, is a fictional character with the power of magnetokinesis, which allows him to control and manipulate magnetic fields. This includes the ability to manipulate metals that are ferromagnetic, such as iron, nickel, and cobalt.

Gold, however, is not ferromagnetic. It is classified as a paramagnetic material, which means it is weakly attracted to magnetic fields but does not maintain a magnetic state once the external magnetic field is removed. Given Magneto's powers are primarily over ferromagnetic materials, he would not have the same level of control over gold as he does over ferromagnetic metals.
