I've been looking at iron filing pictures all day, trying to figure out what is pushing/pulling the magnets around, how it works, how photons are supposed to be involved. It's hard to envisage the shape from those iron filings. Anyone know of 3D pictures of the fields? Or a 3D generator of fields.

 

Pincho.

look up or search for ferrofluid and magnets or magnetics

 

ie:/ "ferrofluid magnets"

 

the pics at the bottom of this page may interest you (there are much better ones with a good search as stated above though).

Ferrofluid is the key though, it`s the only substance within my budget at least that will give an accurate 3d representation of mag feilds

Ok Thanks!

Found some videos

Yes ferrofluid is great stuff.

Well, here is something that you can try.

1.Take a jar, and filll it with vegetable oil

2.Take LOADS of iron filings and put it into the jar.

3.Close the lid of the jar

4.Put two magnets next the the jar,opposite each other, and move them up and down until their magnetic feilds affect the iron filings

5.You should see a good 3d view of a magnetic field lines!

 

I haven't tried it myself though, best the show me the results

Oh my God! I`ve created a Monster!, someone else that`s beginning to think like me! LOL

 

using mineral oil instead of parafin (kerosene) would be a little better as it`s less viscous, and try one magnet to start with, the finer the filings the better the result also

 

 

nice one AOM

Thanx YT. U should be proud of urslef! I am the one who has learnt from you!

GoodBye sweet planet Earth, it was fun while you lasted
