A magnetic field is a region of space that exerts forces on moving electrical charges or materials with magnetic properties. This physical quantity is measured in tesla (T) and is generated through the movement of electrically charged particles, as well as the alignment of magnetic domains inside the magnets. According to the laws of electromagnetism, these magnetic fields originate from the variation of the electric field. Since the way in which the magnetic domains are organized influences the type of magnetism present in the material, materials can be classified as ferromagnetic, diamagnetic or paramagnetic, depending on the strength with which they are attracted or repelled by an external magnetic field.
