Magnetic chuck of lathe machine?

I don't know what your asking, so, a magnetic chuck screws on to the lathe spindle head, the magnetic chuck in its self has a magnet where the polarity can be changed, turn the handle one way and the chuck will hold the part to the chuck, turn it the other way and it releases the part. They also have electrical magnetic chucks and plates, (mostly the plates for this type) this type is powered by electricity through a cord, this type has basically 3 setting, full power on, full power off, and residual, which is around 1/2 power.
