    • Health effects from prolonged exposure to strong fields
    • So, what exactly are magnetic fields? In simple terms, a magnetic field is a region around a magnet or an electric current where magnetic forces can be detected. The direction of the force, also known as the magnetic field lines, depends on the orientation of the magnet or the current flow. Imagine a magnet as a tiny sun, emitting magnetic field lines that radiate outward in a pattern. When these lines interact with other magnets or moving charges, they create forces that can be either attractive or repulsive.

      In recent years, the concept of magnetic fields has gained significant attention in the US, particularly among scientists, engineers, and the general public. As technology advances, we're witnessing the increasing importance of magnetic fields in various fields, from renewable energy to medical research. But have you ever wondered how these mysterious forces work? In this article, we'll delve into the world of magnetic fields, exploring the direction of the force and its underlying mechanisms.
