What is known as 'magnetic energy' is stored in any spatial location where a magnetic field exists. Therefore, a very naive and straighforward answer to your question is that a beam of light (like a laser beam) is a way of storing and focusing magnetic energy (and electric energy as well). This is so, since light is a combination of electric and magnetic fields that travels across space. Since the two always travel coupled, this type of energy is called 'electromagnetic'. I hope this answers your question, Regards, Raul Sanchez
