You have to ask your self, if you are smart enough to learn to use L-rods to detect Magnetic fields? Judging from the idiocy of your rant, apparently not. It's easy to understand that you don't want an LRL to work and destroy your prejudice beliefs.
Really, it's no loss to any one but yourself for any of your false beliefs.
If you want to place L rods in a stationary vice that's your prerogative but it sounds like a stupid, awkward way of using them. Be sure you connect wires to the handles and hold the ends of the wires. A human connection is used to alter the polarity of the Rod(s).
