What element is mostly used in magnets, gold or cobalt?

I would think cobalt because if there was gold in a magnet I think people would be buying a bunch of magnets just to take the gold out

Of course: ) what’s your name ?

Answer is: the equilibrium  shifts toward the reactants, to the left side of chemical reaction.it is because lead(ii) nitrate dissociates in water: pb(no₃)₂ → pb²⁺(aq) + 2no₃⁻(aq).according to lechatelier's principle, the position of equilibrium moves to counteract thechange (more lead cations, common ion), the position of equilibrium will move so that the concentration ofproducts decrease and concentration of reactants of chemical reaction increase.read more on -
