What is Magnetic material? Magnetic materials are materials that exhibit a property called magnetism. Magnetism is the ability of a material to produce a magnetic field, which can either attract or …
What is Ampere’s law? Ampere's law is one of the four Maxwell's equations that describe the behavior of electric and magnetic fields. It states that the total magnetic field around a closed …
What is Hall effect? The Hall effect is a phenomenon where a voltage is generated perpendicular to an electric current in a conductor in the presence of a magnetic field. The Hall voltage, also kno…
Motion in E and B fields Electric (E) and magnetic (B) fields are two fundamental fields that govern the behavior of charged particles. Motion in an electric field A charged particle moving in an el…
What is Ampere’s law? Ampere's law is a fundamental principle in electromagnetism that relates the magnetic field (B) to the current (I) that produces it. The law states that the magnetic field…
Field Due to Moving Charge Particles Electric and magnetic fields are generated by a moving charge according to Maxwell's equations. The electric field (E) due to a moving charge can be describ…
What is divergence? The divergence of a vector field is a scalar quantity that describes the rate of change of the field with respect to position. It is a measure of how much the field is spreading …
What is the refractive index? The refractive index (n) of a material is a dimensionless quantity that describes how much light is bent when it passes from one medium to another. The refractive index …
What is Dielectric materials? Dielectric materials are insulating materials that do not conduct electricity. They are used to separate electrical charges and store electrical energy. When an electric…
What is electric displacement? Electric displacement known as electric flux density is a vector quantity in electromagnetism that represents the flow of electric charge in a dielectric material. It …
What is Clausius-Mossotti equation? The Clausius-Mossotti equation is a relationship between the relative permittivity (εr) of a dielectric material and its molecular polarizability (α). The equation…
What is Electric polarization? Electric polarization refers to the separation of electric charges within a material in response to an external electric field. When an electric field is applied to a m…
What is Potential Energy? Potential energy due to electric charge is the energy associated with the interaction of electric charges. It is a scalar quantity that depends on the magnitude and distrib…
What is multipoles? In electromagnetism, a multipole refers to a distribution of electric charge or magnetic moment that is not uniform. The most common types of multipoles are monopoles (single cha…
