I have worked on old auto generators and if the Permanent Magnet(s) are rubbing against steel or banged around too much, it will lose its field.  These tests we conducted with ceramic Magnets, show no change with the Permanent Magnet, while it does hit the side of what is being used (Magnetic Base for dial indicator).

Difference between radio waves and Wardforce is: 

Radio wave is electronically generated at speeds of 15000 and up.

Wardforce is mechanically generated and controlled at varies speeds.

Drawings show a Permanent Magnet is on one end of the On/Off Induction Switch, NO AIR GAP between the source and the pickup coil (> potential energy), and at different speeds, different reactions are witnessed (torque can be generated)!  What year is this?  We still base everything on OLD TEST, some that were written and are still in a secret language!  I can show you 100 times where someone said, you cannot rub a permanent magnet on a piece of steel, because it will lose its field.  Yet, I show on video that this can be done.
