| Oct 16, 2013 at 4:38 | comment | added | gregsan | straight field lines for magnetic fields are just a small sections of infinitely long magnetic field loops. | |
| Oct 16, 2013 at 4:37 | comment | added | Jitter | Is it still thought that these field lines from the Sun snap? can they form a straight line then? | |
| Oct 16, 2013 at 4:35 | comment | added | gregsan | yes there exists a field before the filings come into the picture, but i am saying the picture does not even show this prior field because the filings themselves alter it (there is no way to depict a field except with a series of vectors or points, both of which betray the actual story and are only used because mathematics require them), causing field concentration near iron, and field gaps where there is no iron, and if you shook everything up, you would not get an identical picture. those lines you see only appear after the fact. | |
| Oct 16, 2013 at 3:51 | comment | added | Sensebe | Your statement that field lines not existing before iron fillings were sprinkled does not convince me.Because,field exist around a magnet even if there is no particle to experience it.And,comparison of lines of drops and the field lines doesn't hold good.Because,field lines have their physical significance(not to be confused with physical existence),but lines of drops has no physical significance.I meant to say that lines formed by drops doesn't exist,if there were no drops,but field exist even if there were particles(existence can be tested by sprinkling iron shavings) | |
