“…9 Consider an elastic waterballoon filled with water. 10 In this case water stands for the fluid while the elastic medium (balloon containing the water) stands for the magnetic field. Both the balloon and the magnetic field, force, in a sense, the water/fluid to behave elastically.…”

“…Thus, from a relativistic point of view it has been found out that interestingly magnetic forcelines do not self-gravitate [3,7,9]. Moreover, they counteract gravitational implosion of a highly conducting fluid and potentially hold it up [5][6][7][8]10]. In reference to this problem and given the elastic behaviour of magnetic fields, one can raise the question concerning the existence of a possible elastic and a fracture magnetic limit.…”

Magnetic fields are a very special form of elastic medium. Within astrophysical environments (magnetized stars and protogalaxies) they counteract shear and rotational distortions as well as gravitational collapse. Their vector nature allows for their extraordinary coupling with space–time curvature in the framework of general relativity. This particular coupling points out the way to study magnetic elasticity under gravitational deformation. In this context, we reveal their law of elasticity, calculate their fracture limit and subsequently argue that they ultimately lose the battle against gravitational contraction of magnetized matter. Two illustrative applications, in a neutron star and a white dwarf, accompany the results.
