EEMAG-1 Course Objectives

• Given a contemporary stastic/quasistatic
  electromagnetic device/system, the student
  should be able to
• Write down the Maxwells equations that describe
  this device/system
• Solve these equations for simple geometries using
  analytical techniques
• Solve these equations for complex geometries
  using MATLAB
