If it is a pure solenoid the air-gap is constant, but the amount of plunger inside the coil varies in a linear way, which may be (but probably isn't) compensated by a linear spring. This is not the case for the typical relay-style electromagnet (also often called a solenoid) where the core is static and attracts a moving arm. -- atp ------------------------------------------------------------------------------ Start uncovering the many advantages of virtual appliances and start using them to simplify application deployment and accelerate your shift to cloud computing. http://p.sf.net/sfu/novell-sfdev2dev _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
