A single "loop" of Wire in a Magnetic Field can be used as a DC Generator. When the "loop" is stationery, it is not cutting any "magnetic lines of force," and the current and voltage are "zero." As the "loop" of Wire is rotated through the Magnetic Field, it starts to break the "magnetic lines of force"; and current and voltage are induced in the Wire Loop. The "magnetic lines of force" induce current into the Wire Loop in the same direction of flow as the "loop" moves in a circle, so the electricity produced is DC since current flow is always the same direction. |
