Micro-addition about “Magnetic Perpetual Motion Machines”.

I have more than a dozen of these magnets hanging in my living room. At first, I made tall stands under each with a glass jar, in order to be sure that they rotate on the suspension precisely due to fluctuations in the local geomagnetic field (“Micro-oscillations”), and not from the movement of air in the apartment.

But it quickly got boring, created unnecessary obstacles to walking and cluttered up the room.

However, if you remove some insulating vessels that protect magnets from convective air currents, then WHERE is the certainty that their fluctuations are caused precisely by changes in the horizontal component of the geomagnetic field???

I thought of it!

I solved the problem “on the contrary”.

It is not necessary to isolate them from the movements of the air, but it is necessary to identify these movements, if any!

I glued thin threads to the magnets and watched it swing around the suspension axis. If the thread ITSELF shifts towards the swing, then this is an air flow. And if the thread is hanging motionless and follows the movements of the magnet, it means that these are NOT CONVECTIVE or any other movements of indoor air. That’s how I found out that magnets swing at different frequencies DUE TO micro-changes in the geomagnetic field that vary in frequency! The resonant frequency of the swing is determined by the ratio of forces of two competing influences: the force of interaction of the magnetic field with the external field and the force of elastic resistance to twisting of the suspension thread itself.

Therefore, the magnetic needles of compasses do NOT oscillate, because THERE is NO RESISTANCE FORCE! Without the force counteracting the rotation of the magnet, there will be no fluctuations!

Even simple copper sheets swing around the suspension axis, but these are DERIVATIVES (the first derivative of the magnitude of changes in magnetic induction over time — dB/dt) of field changes that generate weak Foucault currents (eddy currents in a conductor created by changes in the magnetic field) and their magnetic fields interact with the basic changing fields.

And no cans with coasters!
