1. Electromagnetism 2004 Fall Reference: 《 Electromagnetism, principles and application 》 by P.Lorrain & D.Corson

2. Chapter 1 Vectors Object: to describe the fieds generated by electric charges and currents Mathematical Tools: A field is a function describing a quantity at all points in space.

3. Several kinds : scalar fields, vector fields, tensor fields scalar fields: a single number is given for each point in space ---- well known to us. Example: temperature, pressure, electric potential, etc

4. Tensor are necessary : to unify electric and magnetic fields; to describe the gravitational fields in Einstein ’ s Theory of General Relativity; to deal with strain and stress in solids, etc

5. We focus on vector fields Vector fields: both a number and a direction at all point in space. Examples: electric fields, magnetic fields, current fields of fluid, etc
