1. Coulomb's Law As reported by the Ancient Greek philosopher Thales of Miletus around 600 BC, charge could be accumulated by rubbing fur on various substances, such as amber (or "electron" in Gr
EE3321 ELECTROMAGNETIC FIELD THEORY Lecture 4 Highlights 1. Electric Potential The electrical potential difference is defined as the amount of work needed to move a unit electric charge from the second point to the first, or equivalently, the amount of wo

EE3321 Electromagnetic Field Theory Lesson 5 1. Gauss' Law Coulomb's law is actually a special case of Gauss's Law, a more fundamental description of the relationship between the distribution of electric charge in space
EE3321 Electomagnetic Field Theory Lesson 6 1. Magnetic Field A magnetic field is a vector field that exerts a magnetic force on moving electric charges and on magnetic dipoles (such as permanent magnets). When placed in a magnetic field, magnetic dipoles
EE3321 ELECTROMAGNETIC FIELD THEORY Lesson 7 1. Lorentz Force The Biot Savart Law allows us to calculate the magnetic field B from a current I following a linear path l. AS we will see below, knowledge of B allows us to determine the force exerted on a mo
EE3321 Electromagnetic Field Theory Lesson 8 1. Ampere's Law This law relates the magnetic field B to its source, the current density J. The equation is correct in the special case where the electric field is constant (i.e. unchanging) in time. The law ca
