Magnet Myths and Misconceptions

[MarkE]

Oh-sorry Mark-what would you suppose the gages would be telling you when they are gages that read psi both positive and negative pressures. What gauges would you normaly use when reading water pressure in a pipe?.
Or do I havevto spoon feed you?
Unbelievable

It is not up to me to second guess you.  It is up to you to specify your proposed set-up.

LOL, place a differential pressure gauge across your restriction and tell me which side of the restriction it indicates has the higher pressure.

That would be analogous to a volt meter and doesn't really give much specific insight in my opinion. Knowing there is a difference between two things without knowing the how and why and where specifically is simply a generalization of the facts in my opinion.


Why all our pumps at work have three valves and a gauge to measure discharge pressure, suction pressure, differential pressure and system pressure. We do this because Engineers prefer to know rather than guess at what may be happening. You should try it you may like it.


In any case a gross generalization of the facts and lumped sum measures is generally a losing proposition and the devil is in the details.

I agree with you except for the part I've highlighted. Let's rephrase it so we can agree 100 percent: Storing energy by magnetizing  _permanent magnets_ and attempting to recover that stored energy is inefficient. On the other hand, storing and recovering _mechanical_ energy by using the attractive and repulsive forces associated with PMs, can be very efficient (I think most every pulse motor builder knows that the "cogging" of magnets/cores in relative motion is nearly energy-neutral, that is, an efficient storage and recovery of mechanical energy).

But we see very efficient storage and recovery of electrical energy from magnetic fields every day, all the time. Your computer would not operate, were it otherwise. Nor would radios or many other devices we use every day. Look at the definition of "Q"... the inefficiency comes from losses in a circuit's resistive elements and unintended radiation of power, not from storage and recovery in the magnetic field itself.

    I see the destruction of a magnetic field as an input in energy from whatever is driving the entropy of the Universe.  If a bar of steel is magnetized due to a current flow and the bar becomes a permanent magnet we are facing efficiency problems.  If the same current flow produces a magnetic field change in a transformer that collapses upon cessation of the current then there appears to be some force that is destroying the current produced magnetic field.  It could be ambient heat-electron kinetic energy-basically any force leading to the chaotic side of things.  If we use the current that produces a magnetic field change in a transformer core, to charge a capacitor and then allow this capacitor to charge a second capacitor the efficiency starts to go up and up.  See attached schematic.

Interesting way to look at things.
I have some nice GIF animations about related issue which I cannot post here because this forum's software corrupts GIF files. 
Look, I attached a 141kB file but only 10kB will get downloaded if you try to open or save it 

The same force that destroys the magnetic field in an iron core also rotates two coaxial permanent magnets.

I think you need to check the attitude there Tinman.  You know the drill:  Make your points and advance your argument without drama and without disrespecting others.  I am sure that you have learned a lot of stuff from Mark in the past year or so.

You are dead wrong in the way you think how magnetic fields work as is clearly illustrated sometimes by your choice of words.  Hopefully you will eventually come to this realization yourself.

I need to check my attitude?
Some people just need to see some thing as simple as they are, and not try and show us how big there nuts are. Im doing my best to try and explain what im trying to show in simple to understand diagrams, and professor Mark want the full schematic for the space shuttle.
Do you agree with Mark that water wont flow at the 0 pressure point in the line? If not, why not say something as you would with others MH-AC had the balls to step up.
