MH - What's the opposite & equal of North and South?

Here's the thing about the iron fileings.
In order for them to carry a magnetic field,there has to be one there in the first place.

Another thing to concider is this-if at the (so called)bloch wall,the field is null,then when we place say two 2 inch x 1/2 inch rod magnets together N to S,why dosnt one just drop off, if at the center of the two is a null field?-as the two magnets have just become one long one.
Infact,it is extreemly hard to sepperate those two magnets,and that can only mean there is a very strong field at the center of the magnet-not a null field.

For Tim123:  Let's put the "extra dimension" notion off to the side for now.  Our senses and standard measurement apparatus are perfectly capable of explaining the phenomenon in the clip.

Hi MH

I dont think this is true. As far as I'm aware, physics can only describe the effects - it has nothing to say about the causes.

The vid you posted - they have the 'Left & Right-Hand Rules' - describing the motion. But no real idea as to * why * that occurs, only speculation. Current physics is * totally incapable * of explaining magnetism in general... At least it was the last time I checked...

Magnetism * is * a mystery - as is all of physics if we're honest - that still remains to be revealed. People only * think * they know things...

If we ignore the extra-dimensional stuff when dealing with reality - then all we'll end up with is an approximation.

Regards
Tim
