Magnetic monopoles: particles with pure magnetic charge

by

For over a century, the search for particles with pure magnetic charge, called magnetic monopoles, has fascinated and intrigued the scientific community. Unlike common magnets, which necessarily have two poles, north and south, these hypothetical particles would exhibit a single magnetic pole, thus offering a unique point-like magnetic charge. This singularity raises fundamental issues in … Read more

Magnetorheological fluids: fascinating properties of magnetic liquids

by

Ferrofluids captivate with their unique alliance between the fluidity of a liquid and the powerful magnetic forces of a solid. These suspensions composed of ferromagnetic nanoparticles immersed in a carrier liquid reveal astonishing reactivity when subjected to a magnetic field. The ability of these magnetic liquids to transform, to be magnetized while maintaining their stability, … Read more
