Magnet Myths and Misconceptions

[EMJunkie]

I am posting a picture of aerogel as an analogy to what a magnetic field is like around a magnet.  Forget about the shape, that's not the issue.  The aerogel sort of looks like a cloud of varying density.  Even though the aerogel is of uniform density, with a bit of imagination it looks like it is a cloud of varying density.

You look at the picture and you can imagine the denser parts are like the stronger parts of a magnetic field around a hypothetical magnet that you can't see at the center.  The further you are away from the magnet, the less dense and more wispy the cloud gets, indicating a weaker magnetic field.  Far enough away and the field is so weak that you can't see it anymore, but it is still there.

And for the closed-loop spaghetti strands, they are all there in the sense that if you followed the direction of the magnetic field in the cloud, you would follow the closed loops.  There is an infinity of closed-loop paths in the cloud.

The main point that has been mentioned before, is that there are no "lines of flux to cut."  The "lines" only exist on paper diagrams to help us visualize what is going on.  Typically lines closer together indicate a stronger magnetic field and lines farther apart indicate a weaker magnetic field.

Ok, MileHigh - I am going to agree with SOME of what you have said here. I was going to save this for later on, but after my recent blow off I thought I should bring back some of my frustrations of the lack of Open Mindedness of some people!

After all, we are all supposed to be here to advance the cause, not squabble with each other! This is what we have done and its all we have done!

First, I believe it to be incomplete! But I will advance anyway.

Many years ago, I read something that stuck with me: "as is above so is below" - I cant remember where I read it. There is a movie also called this.

Where I believe you're right is the basic "Cloud" Idea.

Today, the Magnetic Field is considered to be made up of two parts, A and Phi. This is the A Vector Potential, and the Magnetic Field Phi. The A Vector Potential is considered to be an Electric Field.

Like I said, I believe this to be in-complete! I also believe it to be close! Ever wonder why we only get Aurora Borealis near the Poles? Earths Electric Field's repelling other Charged Particles flying in from the Sun? Looking familiar?

We know that the Earth has more than one Electric Field around it! The Van Allen Belts:

Do you believe this to be incomplete because of the Aharonov–Bohm effect ?

[EMJunkie]

I have watched all of Dr. Lewin's lectures available online.  He is a brilliant physicist and teacher. Never once did I ever hear him mention a bloch wall at the equator or on a bar magnet.  So, when you say Chris that he backs you up you are not being genuine.

Bill, just to add further to your comment, your miss-guided representation of the truth may be the result of your misunderstanding of context:

Oh my - MarkE - MORE BAD SCIENCE! Seriously!

Talk about flogging a dead horse! Get some Proof MarkE, stop talking rubbish with no substantial claims. ALL YOUR PROOF is WRONG!!!

Long Solenoid - Physics has already proven you wrong, nearly every science class for some 10 years does this experiment! What part of Experiment can you not understand? Experimental Proof is Hard Fact and yet you still refute it? Why I wonder?

Please go back to school!

Again:

Bill,

I quote again, Walter Lewin: "So the Magnetic Field is really confined in the Solenoid, the Magnetic Field outside the Solenoid, as we discussed earlier, is almost Zero. There is only a Magnetic Field right Here, keep that in mind for what follows!"

Ok, just for some more, real, hard core giggles:

NoBull- No disrespect intended, but for the moment I would rather not say. Certainly the Aharonov–Bohm effect is a very useful tool to examine facts!
