magnfræði
Magnfræði is the Icelandic word for magnetics, a branch of physics that studies magnetic phenomena. It explores the origin of magnetic fields, how they interact with matter, and their effects. Key concepts within magnfræði include magnetism, magnetic fields, magnetic forces, and magnetic materials. The study encompasses both permanent magnets and electromagnets, which generate magnetic fields through electric currents. Understanding the behavior of magnetic materials, such as ferromagnetism, paramagnetism, and diamagnetism, is crucial. Magnfræði is fundamental to numerous technologies, including electric motors, generators, magnetic storage devices, and medical imaging techniques like MRI. The principles of magnfræði are also observed in natural phenomena like the Earth's magnetic field.
