Magnet coil cores, demagnetization power and Lenz delay.

Water is not high pressure steam. Magnetizem and electricity are seperate forces like liquid and gas are seperate states of matter. Magnetisem has no effect on current in a wire. Magnetiizem needs a magnetic inductor to travel through like solid iron or steel just like electricity needs an electrical inductor. Copper's a good conductor of electricity but a poor conductor of magnetisem. The word electromagnetizem is practically meaningless on it's own without a reference to Ampere turns. Ampere turns of wire generate a magnetic field that is indistinguishable from a permanent magnet field. Permanent magnet fields are not  dependent on electricity. This is proof that magnetisem is not electricity as you falsely imply. Both you and Milehigh work very hard to confuse people about the distinct and totally seperate nature of these two individual forces. I threatened to ignore your comments because you persist in acting stupidly about this basic fact.

DLE only relates to the passage of magnetizem through a magnetic inductor and has nothing to do with the passage of electricity through an electrical conductor. stop confusing these differences or I will stop responding to your comments. Both you and Milehigh act like delinquent children and I'm sick of it.

Synchro1 you are asserting statements that are "worse than wrong".   

Steam at any pressure is still water.  True steam is water in the vapor state.

Magnetizem (sic) and electricity are not forces.  They are manifestations of: electric charge, distance, and time.

"Magnetisem (sic) has no effect on current in a wire." could not be more wrong.  Current anywhere has an associated magnetic field. Even at DC current and a static magnetic field causes the Hall Effect.

Highly permeable materials such as you mentioned are very convenient for concentrating magnetic flux.  At medium and high frequencies magnetic flux concentrates between electrical conductors even if the materials have a relative permeability of 1.0 or very close to 1.0 such as air does.  There are objects all around your house that rely on that fact.  There are any number of people who have ignored that fact and come to absolutely wrong conclusions concerning things they measure with electronic instruments.  Steven Jones false claims of 8X overunity from a Joule Thief circuit is a notable example.

Again, electricity and magnetism are both manifestations of: electric charge, distance, and time.  As TK would say: "They are one thing."

Your statement:  "DLE only relates to the passage of magnetizem through a magnetic inductor and has nothing to do with the passage of electricity through an electrical conductor." is utter and total nonsense.  Anywhere charge moves no matter how the path is arranged, there is inductance.  There are no exceptions.  Some arrangements can yield relatively low apparent inductance, such as Aryton Perry wound resistors.  As long as there is distance and time, any current experiences inductive effects. 

I suggest that you avail yourself to any of the many high quality tutorials that are available online.

Officially it's the speed of light, but wouldn't that be weird if the speed is constant, regardless of the medium? All the domains that need to be kicked in iron, compared to rather empty space... Doesn't the speed of sound also vary, depending on the medium?
Peace

But we know that the speed with which electromagnetic waves propagate varies with the medium.

@MarkE,

I never said anything that stupid about the same speed of magnetizem through different materials. Magnetizem and electricityy are not viewed as the same thing for the purpose of this thread. You're acting wickedly on both these falsehoods. You make yourself sound real Smart when you're just full of shit. Tinselkoala's full of shit too!

Synchro1 you are really making quite the fool of yourself.

Look, you assholes want act to act like Albert Einstien. I don't need a "Special Theory of Relativity" to explain "Phase Lag" in a magnet core. All that garbage on Electromagnetizem is worthless for the simple understanding needed to get this effect on a test bench. You over complexify to derail any practical progress.....
