reed switch
Stacy Barros Prof. Tony O Mech. 1 18 March 2015 Reed Switch Explanation When the permanent magnets rotate and getting close to the reed switch making it close and allowing the current to flow. The reed switch is naturally open and when magnet #1 gets close to the reed switch it causes the electromagnetic to push magnet #2 away from the (stator) coil. The battery causes this to happen over and over again until the battery is removed. The smaller the gap between the permanent magnet and the coil as well as the placement of the reed switch will affect how fast the rotor rotates. If the reed switch is not placed properly the rotor will rotate slowly or not at all.
