A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets. Large-scale magnets capable of high magnetic fields are a core enabling technology for many areas of scientific research, medicine, imaging, and energy. The PSFC and Francis Bitter Magnet Laboratory have a long history of developing cutting edge, high-field magnets for a variety of applications.
The most recent research interests include the application of High-Temperature Superconductors to very high current and high magnetic field conductors, magnets for magnetic confinement fusion devices, and for increasing power grid efficiency, reliability, and stability. Another major focus of the research is on the development of very high-field, highly compact cyclotron accelerators for medical and security applications, and laboratory research in nuclear physics. These devices use one of the Low-Temperature Superconductors. Other current programs include Superconducting Magnetic Energy Storage design for an uninterruptible power system, superconducting electrical generator, and motor design for ship propulsion.
One of the best in the field of magnetic research includes magnetic resonance imaging (MRI). Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body. MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to generate images of the organs in the body. Also, researchers at Northeastern University biomedical research centre worked on the MRI machine. Therefore, it may be concluded that the advancement in technology has made human life easy and comfortable but, we must keep in mind, it should not be at the cost of our ecosystem.
