steevey Posted January 23, 2011 Share Posted January 23, 2011 (edited) Problem is simple. Does huge magnetic force affect the light direction ? One of the examples is neutron star. Magnetic force isn't effecting light at all, its the gravity of a neutron star. Strictly speaking, the charge of a neutron star itself is neutron since its made of pretty much just neutrons. However, a neutron star has such a high gravity that the neutrons aren't drifting away from each other. Edited January 23, 2011 by steevey Link to comment Share on other sites More sharing options...
Moontanman Posted January 23, 2011 Share Posted January 23, 2011 Problem is simple. Does huge magnetic force affect the light direction ? One of the examples is neutron star. In a word... No... Neutron stars have outrageously strong magnetic fields, it's difficult to imagine just how strong they are, for me fiction often serves to illustrate this, Dragons Egg by Larry Niven contains a good description of what it would be like on the surface of a neutron star, the magnetic field would be so strong that some directions would be easier to travel than others due to the magnetic field actually being dense enough to prohibit matter from going through the field. This magnetic field is as dense as matter in some places, degenerate neutron matter at that. But light from within the star or from outside it are not bothered by the magnetic field but the gravity field can red shift the light in a big way.

If magnetic effect to the light exist, the light intensity variation around the neutron star can exist. Because magnetic effect have a direction dependent property.

Except it can be proven that magnetism doesn't effect light because objects of neutral charge bend light the same way as an objects WITH charge.

alpha2cen Posted January 23, 2011 Author Share Posted January 23, 2011 Are there no limit at the magnetic force.? Gravity has a limit, Black hole. Link to comment Share on other sites More sharing options...
Realitycheck Posted January 23, 2011 Share Posted January 23, 2011 Google "magnetic lensing". Apparently, it can have a significant effect on cosmic waves and a very minor effect on the visual spectrum. Link to comment Share on other sites More sharing options...
John Cuthber Posted January 23, 2011 Share Posted January 23, 2011 This sort of thing http://en.wikipedia.org/wiki/Faraday_effect might help. However the Faraday effect needs a medium. It doesn't work in a vacuum Link to comment Share on other sites More sharing options...
