Some of the main topics
for Physics chapter Magnetism and Matter (Class 12) along with their details
are:
1) Magnetic Moment: The topic
explains the concept of magnetic moment, how to calculate it, and the different
types of magnetic moments. The learners will also understand the role of
magnetic moment in determining the magnetic behavior of a substance.
2) Magnetization: The topic covers the concept of magnetization, its definition, how to calculate it, and how it varies with temperature. The learners will also understand the different types of magnetization, such as spontaneous, induced, and ferromagnetic.
3) Magnetic Properties of Materials: The topic explains the different types of magnetic materials, their magnetic behavior, and the different magnetic properties, such as susceptibility, retentivity, coercivity, and permeability. The learners will also understand the differences between diamagnetic, paramagnetic, and ferromagnetic materials.
4) Domain Theory of Magnetism: The topic covers the domain theory of magnetism, which explains the origin of the magnetic behavior of ferromagnetic materials. The learners will also understand how the domains align in the presence of an external magnetic field.
5) Hysteresis: The topic explains the concept of hysteresis, which is the lag between the magnetizing and demagnetizing fields in ferromagnetic materials. The learners will also understand how hysteresis affects the magnetic properties of materials and its applications.
6) Magnetic Properties of Solids: The topic covers the magnetic properties of solids, including their magnetic behavior, types of magnetic materials, and how magnetic properties vary with temperature.
7) Magnetic Materials and their Applications: The topic explains the different magnetic materials and their applications, such as in magnetic storage devices, motors, generators, and transformers. The learners will also understand the differences between hard and soft magnetic materials.
8) Curie's Law: The topic covers Curie's Law, which explains the variation of magnetic susceptibility with temperature. The learners will also understand how Curie's Law is useful in determining the magnetic properties of materials.
