Take a tour of the mysterious Red Planet. This virtual globe combines a high-resolution satellite map with laser altimeter data and advanced topographic lighting to present the planet Mars as it appears from above. An Introduction and Guided Tour present some of Mars' most intriguing features. You can leave the guided tour and explore Mars as you like; over 1500 surface features have been annotated with information and links. Mars Globe HD is a must-have app for anyone interested in our solar system. PLEASE NOTE: Regular Mars Globe is a smaller download and is free. This HD version has slightly, not extremely, better resolution and rendering.

Electromagnetic Forces physics app has been designed for K12 students to describe the process of magnetic effect and magnetic force of current. This app helps students to learn about Fleming’s left-hand rule and describes cathode rays structure in an interactive way. In addition, the electromagnetic Forces app illustrates the uses of Cathode Ray Oscilloscope through 3D animations. Each section is explained in detail with diagrams, graphical representations and animations along with simple text explaining the concept. Features of Electromagnetic Forces App: Learn -This section describes the overall process of Electromagnet and Cathode Ray Oscilloscope with 3D animations. Electromagnet - An electromagnet experiment using a wire & Fleming’s left-hand rule to check magnetic effect and magnetic force of current with interactive 3D animations. Cathode rays - In this, cathode rays experimented through CRO (cathode ray oscilloscope) using electromagnetic forces process in an interactive way. 2) Practice - This section helps to practice the working process of electric motor and also observe the variations in sine wave graph with animated 3D experiments. 3) Quiz - Evaluate the knowledge gained from Electromagnetic Forces application through an interactive quiz with scoreboard. This educational application helps students to understand electromagnet and cathode rays in an easy and quick method through interactive animations and experiments. Download the Electromagnetic Forces app and other K12 education apps published by Ajax Media Tech Pvt Ltd to learn physics in an easy and interactive way. Unlike a static or video based education model, which is non-interactive, K12 simulator apps are fully interactive and developed based on adaptive learning.
