Biot-Savart vs. Einstein-Laub Force Law

چکیده
has been verified experimentally when the charge moves inside a magnetic medium for which B is much larger than μ0H [9]. 3 It is sometimes preferable that the force law be given in term of the total magnetic field on the current, in which case it is generally best (in the author’s opinion) to use the Maxwell stress tensor [8]. In 1908 Einstein and Laub [10, 11, 12] argued that the force density could be written in terms of the total H field and the magnetization density M (of quantum magnetic dipoles) in the medium that supports the current law as

About the magnetic field of a finite wire
The Ampère theorem and the Biot–Savart law are well known tools used to calculate magnetic fields created by currents. Their use is not limited to the case of magnetostatics; they can also be used in time-dependent problems. We show in this paper that the highly classical example of a straight wire,generally treated as a simple magnetostatics problem, should be considered in the framework of ti...
متن کاملTrouble with the Lorentz law of force: incompatibility with special relativity and momentum conservation.
The Lorentz law of force is the fifth pillar of classical electrodynamics, the other four being Maxwell's macroscopic equations. The Lorentz law is the universal expression of the force exerted by electromagnetic fields on a volume containing a distribution of electrical charges and currents. If electric and magnetic dipoles also happen to be present in a material medium, they are traditionally...
متن کاملHelicoidal single-layer cylindrical coil self-inductance evaluation: a didactic method
This paper presents a didactic mathematical method to evaluate the self-inductance of a nonmagnetic core single-layer cylindrical and helicoidal coil presenting voids between turns. This type of calculation, using Biot–Savart Law, is not usually presented in the traditional electromagnetic text books, but constitutes an excellent tool to show to the students how to apply the very important Biot...
متن کاملThe Biot-savart Operator and Electrodynamics on Subdomains of the Three-sphere
ABSTRACT. We study the generalization of the Biot-Savart law from electrodynamics in the presence of curvature. We define the integral operator BS acting on all vector fields on subdomains of the three-dimensional sphere. By doing so, we establish a geometric setting for electrodynamics in positive curvature. When applied to a vector field, the BiotSavart operator behaves like a magnetic field;...
متن کاملEquivalence of the Ampere and Biot - Savart force laws in magnetostatics
The equivalence of the Ampere and Biot-Savart force laws in magnetostatics is examined by considering the difference in the forces predicted by the two laws. The conditions under which this force difference vanishes are discussed, with special reference to the question of convergence of the integrals involved. The conclusions are that a complete current distribution exerts forces, which are the...
