Introduction Any concept is made easy with a simplified method of learning. Technology has created a lot of ways for students to learn and understand concepts better. These days kids and teens started to use smart phones. Ajax media has come up with useful learning apps for smart phones.These apps are categorized under the K12 series usable by children from 12-16 years of age helping them in easy learning. About the app

The DC Motor app is made available for both Android and IPhone users. The app aims at: ● Making the students understand the DC Motor concept and the Fleming’s Left Hand Rule ● Attractive images have been used for a much better understanding of the concept ● Self analysis tests can be taken after learning DC Motor A DC motor is a class of rotary electrical machines that converts direct current electrical energy into mechanical energy. The principle behind a DC Motor is the Fleming’s Left Hand Rule. By the Fleming’s

Left Hand Rule, whenever a current carrying conductor is placed inside a magnetic field,

â&#x2014;? A force acts on the conductor â&#x2014;? In a direction perpendicular to both the directions of the current and the magnetic field Working

The direction of this force is given by Fleming's left hand rule and its magnitude is given by F = BIL, where, B = magnetic flux density, I = current and L = length of the

conductor within the magnetic field. If we stretch the first finger, second finger and thumb of our left hand to be perpendicular to each other. ● Direction of magnetic field is represented by the first finger ● Direction of the current is represented by second finger ● The thumb represents the direction of the force experienced by the current carrying conductor ● When armature windings are connected to a DC supply, current flows through the windings ● Magnetic field is provided using permanent magnets ● This creates electromagnetism ● Current carrying armature conductors experience force due to the magnetic field, according to the principle stated above ● Commutator is made to achieve unidirectional torque ● The direction of force is reversed every time when the direction of magnetic field is reversed

DC Motor K12 app explains about the constructive learning of Flemming’s left hand rule and how it is put in operation with DC motor. This K12 app is highly interactive and fun-learning with a 3D animation experiment. Our objective is to make the science concept simple to understand and get in-depth knowledge of the subject. ==Features== Theory - Explains in detail about the DC Motor process and theory applied using Flemming’s left hand rule. Experiment - For the better understanding of students, this app includes a virtual electrical machine to demonstrate the conversion of DC Electrical power into Mechanical power based on the principle of Flemming’s left hand rule using 3D animation. Quiz - An interactive quiz to assess the level of understanding about the topic with a score board. Download the DC Motor app and other K12 education apps published by Ajax Media Tech and make your kids shine in science. Unlike a static or video based education model, which is non-interactive.
