DC Motor

The module is a step by step procedure to make learners grasp the relation between electricity and magnetism. In the first step, the learners start with identifying the position of poles, then differentiating between them, and finally, the interactions between poles of two magnets. Next, they discover the link between flowing charge and the magnetic field, thus getting a hint at origins of magnetism. Finally, using the acquired knowledge (and a little instruction), they construct a device that utilizes both magnetism and electricity to produce mechanical movement. They further manipulate various factors to observe how each modification affects the working of the device and simultaneously confirm Fleming’s Left-Hand Rule.
