re: WATCH: Some very bizarre things happen when you drop a m
erick,Iacob Alex,posted a similiar youtube video on the forum in the past,like yourself i found it interesting and did some experiments ,with different wall thickness's and diameter's of tubing using various strengths of Neo. magnets,i also had a go using a horizontal length of tube sealed at both ends with the floating magnet inside as a pendulum bob which allowed the floating magnet to slow down with each swing and encouraged longetivity of the free swinging pendulum,in truth it was this that introduced me to continue in their use as a medium for a P.M. machine....Good Luck.
As they say - this is normal expected science. Moving a conductor through a magnetic field meets an opposing force, because an electric current is generated in the conductor which causes an opposing magnetic field to be generated. All forces neatly accounted for. This is why the production of electrical energy required the same or greater energy input to turn the generators.
I have long been interested in electrical and magnetic, and many of the ideas and principles can be carried over to gravity PM.
An idea very much related to this electric principle shown here is the Ecklin motor. My understanding of the basic concept is that you forget about forcing a conductor into a magnetic field, for the reason demonstrated above. What you do is manipulate the magnetic field itself to move where you want it to by varying the reluctance of an air gap. Magnetic fields love steel - about 2000 times more than it loves air. So you can direct where the magnetic field goes by moving a steel "flux gate".
Obviously steel is attracted to a magnet (unlike the copper demo above) so there is a force pulling it into the magnet. But, for the same reasons given above) there will be eddy currents in the steel which oppose this attraction. No bother - because at the very same time that you are moving the steel in-between one set of magnets, you have an identical steel flux gate that is being pulled away from another identical set of magnets.
With this situation you have balanced out the torque required to move the flux gate around. With some imagination you can devise many different rotary or reciprocating means of oscillating powerful magnetic fields without any drag on the input motor.
So far so good - nothing unscientific. But the claim is that you can then extract power out of this generator by adding coils of wire to tap the oscillating magnetic flux. Many people have tried, and some have reported very interesting results. I can't fault the logic myself, but the cost of building is a bit daunting.
I think a very similar principle is at work in the Bessler gravity engine - obviously very different forces at work, but the idea of switching the forces as required in a balanced manner is intriguing.
