Nitric acid cannot prepare hydrogen because it is a strong oxidizing agent. When nitric acid comes into contact with reducing agents like hydrogen, it undergoes a redox reaction where it gets reduced to nitrogen gas instead of producing hydrogen gas.

Why concentrated nitric acid is not used to prepare hydrogen gas?

Usually an active metal displaces hydrogen acids. But Nitric Acid is a very strong oxidizing agent i.e. it leads to addition of oxygen to another substancevery quickly . Thus, when hydrogen is formed due to the addition of a metal to nitric acid, it oxidises hydrogen into water. That is why concentrated nitric acid is not used in the preparation of hydrogen gas.

Why hydrogen is liberated when magnesium react with dilute nitric acid unlike other metals where hydrogen is not evolved?

This may due to Magnesium metal has high reactivity and concentration of nitric acid is dilute, thus magnesium reacts with H+ in water/ in nitric acid to give hydrogen
