Hi, I am working on a project, and I need solenoids (so that there is only one pole on a side) that is very small. Something like 1" or smaller in diameter and 0.5" or smaller in height. It doesn't have to be strong. Basically I am going to have a neodymium magnet that attracts the core of the solenoid, and then when the solenoid is turned on, the similar pole of the solenoid will push the neodymium magnet away. Does anyone know where I can get these? I am going to need a lot, what kind of price range am I looking at?
