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).

This game is a fun way to discover the world of crystals and their symmetries through diffraction. Crystals are all around us: in our environment (rocks and minerals, etc), in our bodies (sugar, bones, gallstones, etc.) and in technology (metals and alloys, silicon and quartz used for microelectronics, etc.). By successively discovering the diffraction of X-rays, neutrons and electrons, scientists in the twentieth century threw the door to the microscopic world wide open by demonstrating that crystals are made ​​up of atoms and molecules and explaining their structure. Crystals are characterised by the fact that their constituents are arranged in a highly ordered structure. This internal order and its symmetry is clearly visible in the diffraction patterns produced by any crystal. It is this symmetry which is also gives crystals their often amazing shapes, making them highly prized by rockhounds. Whether you are a senior scientist, a student, or just curious about science, vDiffraction is a serious game that will let you try your hand at crystal diffraction so that you can begin to understand how scientists identify the symmetry characteristics of a crystal. This is the first, crucial step towards understanding the atomic and molecular structure of a crystalline material, in other words what type of atoms and molecules make up the crystal and how they are organised.

Verdict

The call

The clearest difference is price: vDiffraction at Free against Electromag's $1.99. vDiffraction also leads on iOS requirement (8.0 vs 18.6). On ads, in-app purchases and device support there is nothing between them.
