About

EMwaveRT

Features
Read full description

EMwaveRT is an app to aid teaching and learning of electromagnetics (EM) using mobile devices on the topic of plane wave reflection (R) and transmission (T). The app is designed to provide effective touch-based interactivity and visualization to help students better understand EM concepts. It is applicable to EM plane wave reflection and transmission for general oblique incidence and polarization. The instructor is able to input or change various parameters and rotate the view angles for interactive teaching. Based on the parameters, the 3D animations of incident, reflected and transmitted waves can be visualized in real time. This allows the students to identify clearly each wave and improves their learning of plane wave reflection and transmission. Through several preset cases of incident angles, the visualizations on mobile devices are illustrated. The app can be used to supplement the 3D TV program available for download from http://www.ntu.edu.sg/home/eeltan/TEL3DTV.html. User interface: - 3D view may be zoomed or rotated - text view may be zoomed or scrolled - double tap to revert to default view - touch on any underlined field to input/change value - use long slider to change the last field touched - use short slider to change the text transparency - use '|' to show/hide tangential components at interface

The user draws the magnets and the Pic2Mag program draws the magnetic fields. The Field Calculator program now has a Magnetostatic mode, and an Electrostatic mode to plot either magnetic fields or electric fields. The program designed to help students learn Magnetic fields and Electric fields. You can draw magnets and look at the magnetic field, or you can draw electric charges and look at the electric voltage field. The best free magnetic science program you can download! No advertisements, it's just all app. The app can process most images in just a few minutes. The app caches it's results so the more that you use it, the faster the program processes images. Red pixels represent magnets with a North pole surface facing the observer, and Blue pixels represent magnets with a South pole surface facing the observer. Pink pixels represent positive electric charges, and Dark Purple pixels represent negative electric charges
