This past week in class we learned a little about motors, more specifically ac or alternating current motors. These motors use magnets and torque in order to spin a wheel that powers an object. In an ac motor two magnets are placed away from each other creating north and south poles. In between the magnets is the motor which is usually made up of finely woven wires that can be magnetically charged. The third item that is needed is a battery or electric source for power. When the motor is running the motor is being charged by the magnets and, with the electricity moving through the motor, current is flowing in a certain direction. When the motor turns it switches sides but the current always goes in the same direction. Since this happens the motor should flip back the same way so in order to counter that there are many magnets placed so that the attraction force is always there making the motor spin. This is a picture of my garage door opener. It uses an ac motor to open my garage door and although you can't see it from this picture, it is connected to a power outlet on the roof of my garage. This is an example of how we use magnets in our everyday lives.
