Materiales ferromagnéticos: “¿Cómo es eso que el vector H se da vuelta?”

One of the major difficulties that students find in the basic subjects of Electricity and Magnetism is the understanding of the magnetic properties of matter. In particular, the determination of the directions of magnetic vectors in simple devices constructed with ferromagnetic materials such as magnets, transformers and electromagnets. The confusion is compounded by the misinterpretation of B-H curves and /or M-H curves. Textbooks on basic subjects do not address the issue, although it is possible to make a simple model based on the fundamental laws without resorting to advanced knowledge of ...
