  Thank you MH,
        a magnet does not dissipate energy.

Well, take a neomag.  It takes a lot of energy to magnetize it right?  Then, over a period of time (I have heard 100-200 years) it loses its magnetic strength...so... if it is not dissipating that original energy...where is it?  Where did it go?  Or, what did that energy transform/convert into?

Everything should be considered with reasonableness and common sense and balance, don't you think?

When some of the magnetic alignments in a magnet spontaneously decay (increasing entropy) and the total magnetic energy stored in the magnet decreases then that lost energy is converted into heat.  Now of course that's Brad's cue to jump in and say, "See MileHigh is wrong again!"  But we are going to be reasonable and state that for all practical intents and purposes, a magnet does not "dissipate energy" as heat because in the real world it is not measurable.  It's just as crazy as claiming that your flashlight works by drawing energy from the Earth's magnetic field or that when you determine the top speed of a car you have to do it on a slope.  That kind of ridiculous nonsense is just what it is - ridiculous nonsense.

If we split hairs every single time we state something we end up going crazy.  I am not going to live in a nuthouse like that.

I can recall the tinman going hammer and tongs for the old marquee!

I was going to get myself an osillyscope, but virtually no one on here knows
how to use one- perhaps this is a more suitable toy.
Junkie,you sure live up to your name....Junk.

Good Job John, 70+ years to learn that a Tractor of this type can do in 5 minutes what takes a single man all day - That's Progress!!!


If you decide to get a Scope, TK wont be able to help you, he busted his and blamed in on the OEM, MilleHehehehe, he simply forgot about them all together is his fits of Dementia, not many others will be able to help as they all follow OEM Spec on how to use their scopes...

So no hope unless you need one as a Book End?

Keep up the good work old mate - You know, there is a saying:
