• Magnetic Particle Testing (Level 2) Flashcards | Quizlet

    Ferromagnetic materials have some unpaired electrons so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. In these domains, large numbers of atom's moments (1012 to 1015) are aligned parallel, so that the magnetic force within the domain is strong.
