Try this.

Coronal Mass Ejections regularly compress the earths magnetic field.

yeah forgot about this

but the magnetic has give if you will , it bends because it has the space to , bend

but what I was thinking about was the compression of two magentic field in a confined space
 
Magnetic field strength is just a measure of magnetic flux per region of space. A field twice as strong has twice the flux. That's viewable as compressing. What other way could you be referring to?
 
Try this. A light wave is an electromagnaetic wave. It imparts an electromagnetic field as it radiates through space. Or you could say the field imparts the wave. In either case, there is both a magnetic and electric field present and they and the wave are all three mutually orthogonal.

So suppose I say I want to compress the magnetic component of that light wave. What I am really saying is that all three will compress. So what happens is that the wave itself becomes shorter which appears to us as a blue shift in the light, for example.

So how do you do this? I suggest you start with a singularity, then add your wave or whatever your magnetic field source, and Ouila! you have a compressed magnetic field.

I was at the store today and sadly they are out of singularities. However they are running a sale on gravity, so you might want to consider that. A little goes a long way, too!

I disagree

there is space inbetween each right angle

therefore you could compress each angle separately

I don't know what you're saying here, but it also seems clear that you don't either.
 
anyway

what I wanted to know was , have we tried to compress two magnetic fields together in a confined space ?
 
How does a "confined space" have any effect on a magnetic field?

I think you may have a misconception here. Magnetic field lines are not actual lines; they are just a way of depicting magnetic field strength. They aren't actual things that have right angles, although many forces (like electromagnetism) have orthogonally expressed components.

You can concentrate a magnetic field as much as you like by increasing (for example) the current in a solenoid. That would, if you looked at a depiction of lines of magnetic flux, "compress" them into a smaller space.
 
YOU don't compress anything, but if space compresses under gravity the apparent result to an uncompressed observer would be sort of like what he was talking about

fields don't crush together, if that's the idea conveyed in the question. they add.

can we do this ?

and if its done , where is it done ? in what situation

Get two magets - fridge magnets will do just fine.

Turn them so that their "sticky" faces are facing each other.

Now, move them towards each other.

Done.

no because magnetic fields make you sort of rotate , move around them

I want to restrict this movement

what I'm trying to do is find a point the magnetic fields of both , inwhich you could slide on magnetic field into another

not sure yet

perhaps others have some ideas as to how "

to some degree you can reduce a field, but never to zero. it's done by shielding.
 
"inwhich you could slide on magnetic field into another "

a coupler, ferromagnetic core with a pair of coils?
all it does is add them.
