What Are Permanent Magnets?
What are permanet magnets ? A magnetic field is a field created by a magnet. This invisible field is responsible for the most significant property of a magnetic material: it pulls on ferromagnetic materials, such as iron and steel. A magnetic field also attracts other magnets. The strongest magnets have the ability to attract other magnets. This makes them a popular choice for use in a variety of industries. These magnetic fields are what make permanent magnets so powerful. In addition to being extremely strong, they can also be used to develop new materials and processes. The intense pulsed magnetic fields currently used in nuclear fusion research are used to trap hot reacting nuclear plasma, which would melt a solid material vessel. Other uses for permanent magnets involve studying the behavior of semiconductors, such as in micro-sized integrated circuits. In a recent article on the subject, Campbell explains how permanent magnets work, and why they are such important for science
