Magnetic door holders

Anyone know if you can reduce the voltage applied to a magnetic door holder (not maglock) and therefore reduce its field strength ??

Yeah, like the man said, it all depends. But why one earth would you want to do something like that?

Try adding a little spacer to the plate surface to reduce the plate (spacer) to magnet contact area.

Or even a thin plastic film on one side such as a sticker. That will weaken the holding power of the magnet. Double it up and it will be even weaker and you can charge a few hundred $$$ for the work.

Tell your Boss you learned it on PMNation.
