I still contend it was an ambiguous use of the English language as density is a mechanical as well as an electrical term.

I looked up guassian density since I had not heard of it and it is a statistical probability plot not an electrical or magnetic measurement. Of course now I AM curious how you increased magnetic density without changing wire size (thus allowing increased current) or the number of turns of wire (square wire is not the answer either as it merely allows more turns per unit area, EDIT... unless...you put all the windings in a smaller area thus increasing the localized flux thus making the gaussian reference valid). is it because of the material you wrapped the wire on? wouldn't that increase the magnetic field on the (parallel) wrong axis? The motor action would be on the perpendicular axis wouldn't it?

I figure you know something I dont here so teach me



supporting info
The magnetic flux arising in a magnetic circuit is proportional to the magnetomotive force (MMF) creating it. MMF = NI = Φ X R where R is the reluctance of the magnetic circuit.

The magnetic field strength H is the MMF per unit length in a magnetic circuit.
H=NI (N=number of turns of wire) (I= current)


The magnetomotive force is the cause of the magnetic field, the magnetic force is the effect.
