[modeleng] Re: RE Magnetic Chucks.

Dumb question 1 -- Is it actually Electromagnetic and, if so, did you get the 
power source (controller) and try it with that?  [Actually several questions 
here...]
Dumb question 2 -- If it is not electromagnetic, did you turn the knob which is 
supposed to activate and deactivate it?  

Observation 1 -- If it is not electromagnetic and you disassemble it without a 
proper "keeper" between the poles, the magnets will lose much of their 
strength, just like the old two-pole motors for HO/OO trains.
