Winding a strong electromagnet

[capthook]

Testing coil strength for repulsion of a permanent magnet:

Another method for testing coil strength when repulsing a permanent magnet.
A length of wire is stretched taught.  A small permanent magnet is attached to a plastic washer and hung from the wire.  Washer/magnet is then pushed against the coil that is then energized for repulsion and the travel distance is measured.

One of the tests was to determine the difference in winding a coil with 1 wire vs. 2-in-hand (parallel / half the resistance).
It has been proposed that 2-in-hand will outperform as there is half the resistance, thus 2x the amps.

Results: Avg. of 10 tests on each with 9V battery.

Coil 1: 20.4"
1/2"diameter core / #22 wire / 2 1/4"L x 1 1/4" OD diameter coil / 2.85 ohms

Coil 2: 18.7" : 20.5" equalized to coil 1 (1.3ohms x 2= 2.6 ohms : 2.85/2.6 = 9.6% : 18.7" x 1.096 = 20.5")
same as coil 1 but with 2-in-hand / 1.3 ohms

Coil 3: 15.5" : 17.7" equalized to coil 1 (2.85/2.5 = 14% : 15.5" x 1.14 = 17.67")
3/8" diameter core / same as coil 1 / 2.5 ohms


Conclusions:
When results are equalized for small variations in winding accuracy, coil 1 and coil 2 provide identical results.  This is a 3rd set of test data (2 methods/results reported previously) that shows no additional benefit of coil strength by winding with multiple wires.

Coil 1, with the larger diameter core, shows a 15% increase over coil 3.

Further tests with larger diameter cores to come.

How to wind a coil with a larger diameter core?

Attached pictures show a 1-1/4" diameter 1018 core ready for winding.

Winding with an electric drill is much faster, easier and winds a neater coil than trying to do by hand.  But a large diameter core won't fit into the drill chuck.

The extra prep work is worth it - especially having to wind 4 coils.

How do YOU wind your large diameter coils?

I would like to get the highest repulsion between two iron-core coils to demonstrate possible overunity.  The technique is to compare the jumping height of a coil (Output potential energy) with the Input Electrical Energy (via a DSO).

The Coils can have a hole in the middle and the jumping restricted by a non-magnetic rod.

Any useful advice?  Thank you.

If the magnetic strength is dependent on NI where N is the number of turns and I is the current, the chance of getting Output Potential Energy greater than Input Electrical Energy is high.  COP > 1.

The number of turns N is the key factor.

Ferromagnetic core can produce 2,000 times the magnetic strength of air-core. 

The Input Electric Energy to the air-core and the iron-core can be approximately the same but the magnetic strength can be 2,000 times different.

It is obvious that the Input Electrical Energy is not the only source of energy to repel the magnet.  Magnetic energy is lead-out via alignment of the "tiny magnets" inside the ferromagnetic core.

The Output Potential Energy/Input Electrical Energy (COP) is greater than 1.  This is theoretically predicted.  It will be confirmed by Hong Kong University or other top academic institutions.

If COP is greater than 1 in the straight line case, it will also be greater than 1 in the circular motion case.

Thus the 225HP Pulse Motor, the Laing Car, the QMOGENs, the Witts Generators are all theoretically possible.

The Chinese and USA Military Establishments have lead-out energy flying saucers.  Will they disclose such top secret?  What can we do to get them disclose such secrets to benefit the World?
