SUMMARY

The discussion centers on the analogy between gravitational forces and electromagnetic forces, specifically questioning why a magnetic-like force does not exist in gravitation akin to the Biot-Savart law. It highlights that both the Coulomb force and Newtonian gravity share a similar mathematical structure, yet gravitation lacks an equivalent magnetic force. The conversation references the relationship between Maxwell's equations and Einstein's field equations, suggesting that this analogy holds under specific conditions. Additional resources, including a Wikipedia article on gravitomagnetism and an arXiv paper, are provided for further exploration.

PREREQUISITES
  • Understanding of Coulomb's Law and Newton's Law of Gravity
  • Familiarity with Maxwell's Equations
  • Basic knowledge of Einstein's Field Equations
  • Concept of Gravitomagnetism
NEXT STEPS
  • Research Gravitomagnetism and its implications in General Relativity
  • Study the mathematical structure of Maxwell's Equations
  • Explore the arXiv paper on gravitational analogs to electromagnetic phenomena
  • Investigate the conditions under which the analogy between Maxwell's equations and Einstein's field equations holds
USEFUL FOR

Physicists, students of General Relativity, and anyone interested in the fundamental forces of nature and their mathematical relationships.

the coulomb force and the Newtonian law of gravity have the same structure:

F_C=\frac{q_1q_2}{R^2} and F_G=\frac{m_1m_2}{R^2}.

so why isn't there an equivalent to the magnetic force in gravitation? so that one could imagine a law of the same structure as the biot-savart law for gravitation. is there something like that? and when not, why? what is so different in gravitation?

Such a concept has been discussed. In fact an analogy between Maxwell's equations and Einstein's field equations can be made, valid only under certain limiting conditions.

I don't know much about it, so I will leave any more in depth explanation for those more familiar with the material.

There is, however, a wiki article on the topic:

http://en.wikipedia.org/wiki/Gravitomagnetism

and of course, the arXiv is great:

http://arxiv.org/abs/gr-qc/0311030
 
Thank you G01! this is exactly what i was looking for. i wonder why this wasn't told in my introduction courses in physics, and none of my fellow students knew about that. guess i had to take the General Relativity course, to get to know about^^
