SUMMARY
The energy density of Electric and Magnetic Fields is defined by the equations (ε/2)*E² for electric fields and (1/(2μ))*B² for magnetic fields. These expressions can be derived from the principles of electromagnetism, specifically using examples such as a flat capacitor and a solenoid. The discussion references equations 595 and 950 from the University of Texas lecture notes, which provide detailed derivations of these formulas. Understanding these concepts is crucial for grasping the fundamentals of electromagnetic theory.
