Then the claim that a super conductor requires no power input-->rubbish,the power input is in the form of cooling,
Nope, cooling subtracts energy from matter - it does not add energy.
This is elementary.

Some what correct,but as there is a dead short through the magnetic material,then no electrical charge potential can be detected between or at the pole ends.The effect is very similar to that of static charge attraction,and that is why i used static charge as an example.
 

So you are indeed referring to electrical charges?

What is keeping the charges separated in that conductive ("dead short") magnet?  Due to the "dead short", why don't the charges just dissipate/equalize as they do in all other conductive materials with respect to static charge?

What about non-conductive ferrites?  Should not an electroscope or electrometer respond to the bunched charges proposed to exist at the poles of a non-conductive ferrite PM?

Conversely, why are "static charged" balloons, combs, and plastic rods not magnetic?

Don't get me wrong, I realize the current understanding is far from complete, but are you actually proposing that magnetic attraction/repulsion between PM's is due to attraction and repulsion of electrical charges in those PM's?

Kindly show me there are not.

No Tinman, you cannot ask him to do that.
There is a simple reason for that - it is impossible to prove an existential negative.

In case you ask "Why?" I will answer that preemptively, because: "a lack of proof of existence is not a proof for nonexistence".

However it is possible to prove an existential positive (that something exists), thus the burden of proof is on you.
And yet when i ask the question-please explain what or how a magnetic field exerts a force on a magnetically active material useing your current magnetic field modle,no one can come up with an answer. The very same happens when you ask why are two masses attracted to each other=gravity. Then we get-the magnetic field acts like gravity ???
Here we have one unknown trying to show or represent the same effect as another unknow,even though the two unknows are different.

How far are we behind here?. I will show you how little we have learned in the passed 200 years.
We still dont know(even though we apparently have this well proven modle)how a magnetic field exerts a force on a magnetically active material.
We still dont know why gravity works the way it dose-the best we have is that two masses are attracted to each other because they have gravity ::)
Go and try to find a definitive answer as to how the charge is formed that creates lightning.
Example 1-Quote: Now, the cloud becomes a thundercloud. Lots of small bits of ice bump into each other as they move around. All these collisions cause a build up of electrical charge.

Cool,now we can make electricity by throwing snow ball at eachother.

Example 2-Quote: Eventually, the whole cloud fills up with electrical charges. Lighter, positively charged particles form at the top of the cloud. Heavier, negatively charged particles sink to the bottom of the cloud.

And yet the lightning is attracted to the ground. Why dosnt it remain between the two different charge potentials.

So you see NoBull,you ask me to proove my theory,and yet the unknown is still acceptable within the science comunity-and amoungst many here.

200 years later,and the current modle of the magnetic field still has no answers to give. It's an attitude of-it work's,so leave it alone.
Do you see us going any further if we dont start to question that which has not progressed in 200 years. Will you be happy with the same old internal combustion engine for the rest of time?.

The solar panel is one of the greatest inventions of all time,and this is what we need for a magnetic field-a panel that exchanges a magnetic field for electrical energy. I am simply throwing a theory out there that seems to dot all the I's,and it is just a theory-just like many theories out there today in the scientific comunity.If we fully understand how something work's,then we can explain as to why it has the effects it dose-the current magnetic modle dose not do this,so it's time to look elsewhere.

Please show me a device that can cool matter that requires no energy to do so. Liquid nitrogen is made how? if not by a device that requires energy.

I am refering that these particles may act like electrical or static charges.

A decent 12 volt SLA will have only around a 1.2 ohm internal resistance,why dosnt it go flat?.As the particles are yet unknown,and this is just a theory i am presenting here that may explain the missing link,i dont have all the definitive answers you may seek just yet. But if you ask how todays modle of the magnetic field attracts or repell's magnetically active object,you will still get no answer.

Again,i have no answer to exactly what these particles may be,so i cannot answer your question above.

It is odd that the 3rd responce to the meaning of magnetic when a search is done on google is -Quote: 3.very attractive or alluring.

Quote

As i have stated before,i dont know what these particles are or what there structure may be. But i do believe that they are particles that have an opposite charge to one another. wether that charge is electrical or not is unknow. The word charge has many different meanings,and electrical is only one.

If we cannot complete the current understanding useing the current modle,then maybe it's time to look at another modle that has the same effect as the current,but also gives answers to the cause as well.

Aint that a hoot. totally opposite to that if we use a PM. ;)

No, it is very very very basic:  The screwdriver, or nail, or whatever other soft material retains a small part of the magnetic alignment that it is exposed to.  Insert it into an electro magnet where N is towards the end of the screwdriver and field is aligned N-S from the tip towards the handle because that is the way that the field is pointing.  You have put the screwdriver tip in the middle of the magnet.  If you were to construct a long cylindrical magnet magnetized along the long axis and insert the screwdriver into the center of that magnet and then withdraw the screwdriver you will get the same orientation result as doing the same thing with an electro magnet or by inserting the screwdriver into an electromagnet and then shutting the electro magnet off.

Tinman,

Just because science does not yet have all the answers does not mean that they are not being sought out.

There is a great deal of research ongoing with regard to our understanding of gravity and magnetism.  I think this century will provide some very astounding answers.  The pieces have already begun to fall into place, particularly over the past decade or two.  The complexity and precision of recent and ongoing experiments and instrumentation is amazing. 

On a much lighter note, did you watch this video?  Although the methodology used leaves some room for discussion, I though it was pretty cool.

This would be hard to test and confirm,as to remove the screwdriver from within the long cylindrical magnet,the tip of the screwdriver must also pass through the opposite field.If the field of a PM flows out of the north end befor it makes a turn and heads south,then shouldnt that part of the field represent the field around the electromagnet setup? With an air core electromagnet,the field curls back into the center of the coil as well,but once the screwdriver is inserted into that coil,the field dose not curl back into the center,but forms a field the same as that of a solid PM.

I hope the outcome is good,and soon,as im getting older every day. Some times i get sick and tired of waiting for answers that just dont seem to come,so i go looking elsewhere. I see no harm in presenting an alernative theory,and one that seems to fit better that the current in providing answers. But with this comes more questions-what could these particles be?. Well there in lies the problem-i have no means to find out. But what if it's an opportuinty missed just because some are stuck with the current modle. If you had seen what i have seen every day for the past two year's,then you to would be starting to question the reality of the current understandings.

Something is missing here,and im just looking around -so to speak.

I havnt yet,and the bad thing is i have to leave for work again at 2am-i should be in bed getting some sleep right now,but the brain wont rest. Another week on the road ahead,so may be some time before i get to see it. I might go have a look now,and if it's not too long,then i will sit it through.

No it is easy to test.  A solenoid is easily constructed or purchased.  Hollow cylindrical IE donut magnets magnetized along the short axis are also readily available.  You created an apples and oranges comparison by placing the screwdriver inside the EM, but next to the PM.  If you don't want to withdraw the screwdriver then shatter the PM while the screwdriver is still inside, or wrap the screwdriver in high temperature insulation and heat the PM past its Curie temperature.

Perhaps. But at this point in time,i dont feel it's mine to show.Feel free to contact Chet,he knows what it's all about,because at this time ,i must get some sleep and then hit the road. I wont be back on my computor until friday,and the phone is a right pain in the a-s to try and use to comunicate through here.
