Cobalt

Cobalt is a chemical element with the symbol Co and atomic number 27. Like nickel, cobalt is found in the Earth's crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal.

Cobalt Metal Characteristics

It is one of the three naturally occurring magnetic metals (iron and nickel being the other two) and retains its magnetism at a higher temperature (2012°F, 1100°C) than any other metal.In other words, cobalt has the highest Curie Point of all metals. Cobalt also has valuable catalytic properties

Is Nickel Magnetic

It may be that the Nickel (Ni) in the nickel coin somehow disrupts the electrical currents. This seems possible since adding Nickel (Ni) to Iron, Carbon, and Chromium a form of stainless steel is created that is not magnetic even though it contains Iron. But dimes and quarters have Nickel as well, just less.
