Electromag is an educative application in support to a high-school or university course of electromagnetism. It contains not only a memorandum of the basic equations, but it also contains approximately twenty animations illustrating the various concepts of electromagnetism. This application runs also on iPad and iPod Touch 3rd generation and later. 50 screens of electromagnetism! For teachers !! Connect your iPad with a video projector and show the animations to your students in classroom. List of covered subjects: Electrostatics: Coulomb'sLaw, Electric Field, Gauss Theorem, Electric Potential, Capacitance. Electric Current: Current and Resistance, Circuits. Magnetism: Magnetic Field, Magnetic Fields Due to Currents, Electromagnetic Induction, Inductance. Electromagnetism: Maxwell Equations, Wave Equation. Physical Constants. Each section contains at least one animation of which some in 3D. List of animations: - Coulomb's law, - Electric field lines, - Movement of a charge in electric field, - Electric dipole, - Lead-acid battery, - Torque on a current loop (in 3D), - Charge in magnetic field, - Cyclotron, - Induction field due to a current in a long straight wire (in 3D), - Generator (in 3D).
Wittgenstein
Read full descriptionHide full description
A slow, careful encounter with Wittgenstein's Tractatus Logico-Philosophicus. Each proposition appears as a fill-in-the-blank — one word missing, two options to choose from. You read carefully, weigh each word, and feel why Wittgenstein chose this one. The Tractatus, from "The world is everything that is the case" to the closing silence. Faithful to the Ogden translation. Five propositions per day are free. A one-time purchase unlocks the book — yours forever. No ads. No tracking. Fully offline.

Verdict
The clearest difference is price: Wittgenstein at Free against Electromag's $1.99. Electromag's advantage is in-app purchases (none vs 1). On update cadence, ads, device support and iOS requirement there is nothing between them.
