More model informationThere is a constant magetic field (brown lines), inside of which we make a coil rotate at constant speed. The result is an alternating current is generated. Why alternating? The magnetic field created by the current (purple) in the coil will always try to opose the original field, so the current should flow on the direction of the green arrows. To achieve this, it must constantly change direction to adapt to the rotations of the coil, resulting in the blue current.
