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.

Move light. Refract it. Reflect it. Light Lab is an interactive science app where you learn by playing with light. 【Discover the Magic of Light】 Touch the screen and move the light source. Rotate lenses and change refractive indices. Watch light rays change in real-time! Create rainbows, bounce light off mirrors. "Why does this happen?" As you play, you'll naturally understand how light works. 【Perfect For】 ・Students learning about light in elementary or middle school ・Anyone studying light propagation, reflection, and refraction ・Teachers who want to make science class more engaging ・Anyone curious about optics 【What You Can Do】 ◆ Real-Time Light Manipulation Move light sources and lenses to see light rays change instantly. Rotation, translation, refractive index changes—all operations reflect in real-time. ◆ Place Various Lenses Triangular prisms, convex lenses, concave lenses, diamonds, spheres, mirrors, and more. Place up to 10 lenses simultaneously to recreate complex light behaviors. ※2 lens types are free (triangle prism, biconvex lens) ◆ 3 Types of Light Sources ・Parallel: Like sunlight ・Spotlight: Like a light bulb ・Dispersion: Rainbow-colored light ◆ Create Animations Save lens and light arrangements as "scenes." Connect multiple scenes to create animations showing how light transforms. ◆ Save and Share Save your creations in the app. Generate QR codes to share with friends and classmates. 【For Teachers】 Designed as an educational tool for classroom use. ・Visually understand light propagation, reflection, and refraction ・Simulate phenomena that are difficult to explain, like total internal reflection and dispersion ・Students can experiment independently—perfect for inquiry-based learning ・Save and share scenes as teaching materials Try it for free first! 【Features in Detail】 <Light Source Adjustments> ・Position and rotation ・Adjust number of rays and width <Lens Adjustments> ・Position and rotation ・Refractive index settings ・Size adjustment ・Curvature adjustment for convex and concave lenses <Scene Features> ・Create up to 5 scenes ・Smooth animations between scenes <File Features> ・Local saving ・QR code sharing 【Pricing】 Basic features are free. ◆ Lens Unlock ($5.99/ One-time purchase) Unlock premium lenses (plano-convex lens, biconcave lens, diamond, sphere, mirror, reflector). ◆ Lens Ticket Issuing Feature ($11.99/ One-time purchase) ※Requires "Lens Unlock" purchase first Generate QR codes to unlock all lenses on other devices for 1 year. Tickets can be issued repeatedly—perfect for teachers adopting the app school-wide or classroom-wide. 【Privacy】 ・No personal information is collected ・Works offline by default ・Internet connection required only for accurate time retrieval when using Lens Ticket feature 【Requirements】 ・iPhone / iPad ・iOS 16.0 or later 【Support】 Detailed instructions are available in the in-app "How to Use" menu. For questions, contact us via the support page. Bring the world of light closer. Let's play with light!

Verdict

The call

The clearest difference is price: Light Lab at Free against Electromagnetic Forces's $0.99. Light Lab also leads on update cadence (every 3 months vs every 32 months). Electromagnetic Forces's advantage is in-app purchases (none vs 2) and iOS requirement (12.0 vs 16.6). On ads and device support there is nothing between them.
