Magnet Myths and Misconceptions

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.

Cheers
