    Is cobalt a magnet?
    A lustrous, silvery-blue metal. It is magnetic. Cobalt, like iron, can be magnetised and so is used to make magnets. It is alloyed with aluminium and nickel to make particularly powerful magnets. Other alloys of cobalt are used in jet turbines and gas turbine generators, where high-temperature strength is important.

    What is cobalt used for?
    Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays. Cobalt is also used in the petroleum industry as a catalyst when refining crude oil. This is to purge it of sulfur, which is very polluting when burned and causes acid rain. [ 9 ]
