The phenomenon described in the question is when the particles of an object are fully aligned to one side, causing a strong attraction or repulsion effect. This is characteristic of ferromagnetism. In ferromagnetic materials, the magnetic domains are aligned in the same direction, resulting in a strong magnetic field. This is in contrast to other types of magnetism such as diamagnetism and paramagnetism, where the magnetic domains are not aligned and the magnetic field is weaker. Magnetism is a general term that encompasses all types of magnetic phenomena, including ferromagnetism, but the question specifically describes the phenomenon of ferromagnetism.
