Electromag vs Huygens3D

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).

Huygens3D brings the exploration of fundamental wave phenomena to iPad and iPhone, making it a full alternative to the classic ripple tank in physics lessons. Interference, diffraction, reflection and refraction are simulated just like in a real water tank. Thanks to the intuitive controls, every experiment is set up in seconds, so all students can experiment on their own. Features: • various wave sources (point, line, points on a line, circle), as a continuous wave or a wave packet • various obstacles, slits, prisms and lenses • rain field for random waves • pause and step-by-step mode • phase probes with an oscilloscope view showing the phase difference • tape measure for measuring in length units and in multiples of the wavelength • screen showing interference and diffraction patterns • share experiment setups via AirDrop, Messages or Mail
