2: Electric and Magnetic Fields

- 2.5: Magnetic Flux Density
- Magnetic flux density is a vector field which we identify using the symbol B and which has SI units of tesla (T). Before offering a formal definition, it is useful to consider the broader concept of the magnetic field. Magnetic fields are an intrinsic property of some materials, most notably permanent magnets.

- 2.8: Electromagnetic Properties of Materials
- The electromagnetic properties of most common materials in most common applications can be quantified in terms of the constitutive parameters ϵ , μ , and σ, which are the teh Permittivity, Permeability and Conductivity. These are the three constitutive parameters, which describe the effect of material in determining an electromagnetic quantity in response to a source.
