The magnetocaloric effect: cooling by magnetic fields

by

The world is increasingly turning towards environmentally friendly energy solutions. Among these innovations, magnetic cooling emerges as a promising alternative, strongly rooted in the physical phenomenon known as the magnetocaloric effect. This natural phenomenon illustrates the ability of certain materials to change temperature under the influence of a magnetic field, paving the way for energy-efficient … Read more
