Magnetizing a Material Without Applying an External Magnetic Field
Publicado em 03 agosto 2021Researchers propose a method of magnetizing a material without applying an external magnetic field.

The process aligns the spins of the material’s particles and magnetizes the system. Magnetizing a material without applying an external magnetic field is proposed by researchers at São Paulo State University (UNESP), Brazil, in an article [...]ver notícia
