Section 15: Magnetic properties of materials
2013-2-26 Section 15: Magnetic properties of materials Definition of fundamental quantities When a material medium is placed in a magnetic field, the medium is magnetized. This magnetization is described by the magnetization vector M, the dipole moment per unit volume. Since the magnetization is induced by the field, we may assume that M is proportional ...

Magnetic Properties of Materials
2020-4-2 A magnet is a material or object that can produce a magnetic field. This magnetic field is invisible. However, it is mainly responsible for the most notable property of a magnet. According to these magnetic properties, a magnet possesses a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other

Section 16: Magnetic properties of materials (continued)
2013-2-26 Section 16: Magnetic properties of materials (continued) Ferromagnetism Ferromagnetism is the phenomenon of spontaneous magnetization – the magnetization exists in the ferromagnetic material in the absence of applied magnetic field. The best-known examples of ferromagnets are the transition metals Fe, Co, and Ni, but other elements and alloys ...

Chapter 8: Magnetism Electromagnetism
2017-1-17 The magnetic field lines surrounding a magnet actually radiate in three dimensions. These magnetic field lines are always associated with moving charge. In permanent magnets, the moving charge is due to the orbital motion of electrons. Ferromagnetic materials have minute magnetic domains in their structure. The Magnetic Field
