There was once a company selling devices which contained
a large electro-magnet "loosely" connected to a metal bar.
The entire unit weight was about 6-7 pounds. A Hefty device.
There was a on/off switch and a pilot light.

The metal bar is secured to house plumbing. The electro-magnet
then VIRBATES at 60hz. There is a CHATTERING sound that is transmitted
into the pipes.

The theory is that the 60Hz buzzing drives the rodents crazy.

??????????????????????????

Does it work? I don't know.
