If it's non-resistive it's purely inductive, so v=-L*di/dt right? So if current i is constant, voltage v is zero, therefore consumed power i*v is zero, and so is consumed energy i*v*t. So as I said, "a non-resistive current loop would not consume any energy to keep the current going". > > Now this may come as an even bigger surprise to you, but a pure inductance is in fact unable to consume _any energy at all_, even if current is not constant. It can store energy (1/2*L*i^2), it can transfer energy when mutual inductance is at play, but it just can't consume any. Resistance can consume energy, reactance can't, any textbook will tell you that.
You still do not see it. Back to your quote, "You keep telling us electromagnets consume energy, true but that's ***ONLY*** because the wires are resistive." Lets consider an electro-magnet that has no wire resistance. We energize the coil, which moves energy from the battery to the near and far field. Right off the bat we have unrecoverable energy lost in the far field ... with no wire resistance. :-))) Now to continue, near the electro-magnet is another electro-magnet. This electro-magnet accelerates toward our original electro-magnet, which induces an opposing voltage against the original electro-magnets current. This consumes energy from the original electro-magnet in the amount of the opposing voltage times the current. Then the electro-magnets turn off to collect some of the original energy. The amount of energy lost during the entire process is equal to far field loss plus KE energy gained. :-) > P.S. The confusion over the definition of "universe" is yours (and shared by all people talking about multiple universes) I am afraid. As I said the universe is all there is, by definition: > http://www.thefreedictionary.com/universe > as can be easily understood from such derived words as "universal". If you dislike the word, "nature" is fine for me too. You still don't seem to understand. Even the same website clarifies if you took the time to lookup Omniverse --> http://encyclopedia.thefreedictionary.com/Omniverse Quote, "In physical cosmology, omniverse is a term used to differentiate a limited number of ***universes*** from all existent universes." Take note of the plural word "universes." Again, the definition of "universe" is in the process of changing, now that we are accepting existence beyond our universe. > No offense as you like to say, but isn't this an excellent occasion to show us how gladly you admit being in error Paul? ;-) So far I am not in error, and it seems you are not willing to claim your 2nd and 3rd error.
