Negative Inductance and measure of Magnetic force.

[synchro1]

I'm converting this choke into an extremely powerful electromagnet, hacksawing the "I" off the "W" stator by hand. The inductance of the 500 Newton coil is .75 Henries. With a MU of 7000, the magnetic attraction strength from the silicon steel lamination core coil should be around 1300 pounds! That means it will be generating 13 times the magnetic field strength of the cheap electromagnet for the same power input.

The power of MU!

Here's the 10 Henry electromagnet in action:

The round magnet with a cobalt core and MU of 250, generates around 100 pounds of attraction force. The higher Henry "E" core of silicon steel laminations with a MU of 7000 would generate many times the attraction force for the same input!

Assuming we generate more attraction force with the higher permeability electromagnet then the electromagnet with lower core Mu, with the same input power. Here's the question: Will the higher permeability core coil generate more output then the coil with less permeability from a rotor magnet of equal strength and force? For example; Let's say we simply roll a powerful neo magnet sphere into each coil core powered by magnetic attraction alone and measure the output from the collision. Will the coil of higher core permeability generate power in the same proportion it generates a magnetic field from input to the one of lower value? In other words, would the higher Henry coil generate many times the electrical power as the round EM coil of less inductance from the motion of a permanent magnet of equal strength and force of motion? The answer is a categorical "yes", based on the test results I performed and recorded throughout the course of this thread. The strength of the EM's can easily be tested by attaching a permanent magnet of known gauss, and seeing if the coil can drop it with a neutralization pulse.

I replaced the battery in my "VICI" Inductance meter, and remeasured the inductance of the two electromagnet coils.

The 10 Henry choke, which measured 10 Henries when I first got it, now measures 1.91 Henries with the core split.

The 500 newton round coil, which has been used mightily by me, now measures .052 Henries. It generated a little over 100 pounds of attraction strength new, but has grown weaker.

Nevertheless, the silicon steel laminated "E" core EM coil currently has a whopping 36.7 times the inductance as the round cobalt core EM.

That means the round EM coil would need 36 times the power to do the same work as the laminated one. That would surely make it smoke!

The corollary, of course, is that the silicon steel core coil would generate over 36 times the power from the same magnet rotor as the round EM.

O.K., now for a final exam see if you can make sense of the following statement:

The EM coil is in the presence of a magnetic field with a value of one "Negative Henry".

The core saturation from the adjacency of a permanent magnet field would lower the core inductance from 1.92 to .92. and therefore have a value expressed in 'Negative Henries".
