Course Description
Fundamentally, this course focuses on the basic laws that govern static electromagnetic
fields such as Coulomb’s law for electrostatics and Biot–Savart’s law for magnetostatics.
Based on these laws, the nature and properties of electrostatic and magnetostatic fields
in material spaces, with real-world applications, are explored.
The major topics include:
• Vector algebra and calculus as a mathematical foundation.
• Electrostatics: Coulomb’s and Gauss’s laws for static charge distributions.
• Magnetostatics: Biot–Savart’s and Ampere’s laws for steady currents.
• Maxwell’s equations for static and time-varying EM fields.
Course Objectives and Competencies
Upon successful completion of this course, students will be able to:
• Understand and quantify electrical effects of static charge distributions.
• Apply electrostatic laws to various charge configurations.
• Analyze effects of charges moving with uniform velocity.
• Understand the fundamentals of electrodynamics.
• Summarize electromagnetism using Maxwell’s equations.
