Detailed description (min 1,500, max 2,000 characters incl. spaces/line breaks):
The cooling industry stands at an inflection point. Synthetic refrigerants carry well-documented environmental burden, while natural alternatives bring their own practical and regulatory challenges. Together, these pressures are accelerating the search for fundamentally different approaches to cooling. Among these, magnetic cooling has emerged as one of the most promising: a refrigerant-free technology using the magnetocaloric effect, a thermodynamic response of specialist magnetic materials to changing magnetic fields.

Over the past decade, magnetocaloric technology has progressed from laboratory curiosity to demonstrable cooling systems, with ...
