Key Points

Maxwell’s FOUR equations describe how electric charges and currents create electric and magnetic fields, and how they affect each other.

Gauss’s law relates an electric field to the charge(s) that create(s) it.

Gauss’s law for magnetism states that there are no “magnetic charges” analogous to electric charges, and that magnetic fields are instead generated by magnetic dipoles.

Faraday’s law describes how a time-varying magnetic field (or FLUX ) induces an electric field. The principle behind this phenomenon is used in many electric generators.

Ampere ‘s law originally stated that a magnetic field is CREATED by an electrical current. Maxwell added that a changing electric flux can also generate a magnetic field.

Key Terms

differential equation: An equation involving the derivatives of a function.

flux: A quantitative description of the transfer of a GIVEN vector quantity through a surface. In this context, we refer to the electric flux and magnetic flux.
