A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...
“The electric and magnetic fields at a material’s atomic level determine its bulk properties and behavior, and are an essential area of research,” says Toshiaki Tanigaki, a senior researcher ...
A solution proposed by a team of scientists at the North Carolina State University is a metamaterial that can change shape in response to magnetic fields. This material had to be easily deformable ...
