Hello! I have a question about something happening when I am running a device that has been created. I am not going to go into detail yet specifically what this device does, or how it functions, just that it uses high frequency changing electric and magnetic fields. and is set up similar to a "tower".
the other day because I love to try new and sometimes pointless things purely out of curiosity. I had an old armature from a car starter motor laying around directly on top of the device or "tower" with a bottle cap in between any metallic surface that may cause electricity to flow through it .
The armature was placed on the op of the tower without any connections or wires, it was just resting on top of this "tower" while running this device and sweeping through the frequency's there was at one point and a certain frequency that the armature that was placed on top of the tower starting spinning very fast in the counter clockwise direction.
I have not investigated the cause of this further, i am just wondering what would cause this to happen and how "strong" such a field would need to be to cause an armature to move in the absence of any local magnets.
