Grapholite is an easy to use, touch-friendly, inexpensive, yet very powerful alternative to Visio that can be used for all types of business graphics: flowcharts, floor plans, office layouts, uml diagrams, organizational charts, mind maps, venn charts, bpmn diagrams, web-site structures and wireframes, technical drawings, network layouts, ui mockups and much more.
Magnetostatics shifts the focus to steady, non-time-varying electric currents.
If you need a digital copy of "Electromagnetic Field Theory and Problems" by T.V.S. Arun Murthy:
The book's strength lies in its logical and comprehensive organization, covering topics from basic math to advanced applications. One listing highlights fourteen chapters, starting with essential mathematical methods and building up to radiation and antennas. Here is a more detailed look at the chapter flow, based on another library catalog that breaks it down into eleven chapters: Rather than treating Maxwell’s equations as an isolated

Work done, potential difference, conservative fields, and the potential gradient. Before writing down any formulas
Rather than treating Maxwell’s equations as an isolated crowning chapter, Murthy references them early and often. When solving a magnetostatic problem, he will note: “This is a static case of Ampere’s law, which is one of Maxwell’s equations. But in the time-varying case (Chapter 5), the displacement current term would appear.” This builds conceptual continuity.
: Used for rectangular geometries like parallel-plate capacitors. Ideal for coaxial cables and cylindrical conductors. Spherical Coordinates : Perfect for point charges, dipoles, and antennas. Differential and Integral Calculus and antenna arrays.
EM wave propagation, polarization, reflection, and refraction. Guided Waves Transmission lines and waveguides. Radiation & Antennas Radiation basics, antenna theory, and antenna arrays. Key Features for Students Problem-Solving Emphasis:
Every theoretical derivation is followed immediately by step-by-step solved problems.
Electromagnetics problems often require cross-referencing formulas, constant values, or specific boundary conditions. A PDF allows students to search for terms like “coaxial cable capacitance” or “TE10 mode” instantly—impossible with a physical book during an open-book exam or last-minute revision.
Before writing down any formulas, draw the charge or current distribution. Visualizing whether a problem requires cylindrical or spherical coordinates eliminates fundamental errors early on.
