WebOct 19, 2024 · Describing the field of a moving charge requires a scalar potential φ and a vector potential A. The two potentials determine the two fields as follows: E = − ∇ φ − ∂ A ∂ t, B = ∇ × A. Together φ and A make up the four components of the “four-potential” A μ, a Lorentz four-vector. So although φ is a scalar under rotations ... the greatest tyrannies are always perpetratedWebMagnetic scalar potential, ψ, is a quantity in classical electromagnetism analogous to electric potential.It is used to specify the magnetic H-field in cases when there are no free currents, in a manner analogous to using the electric potential to determine the electric field in electrostatics.One important use of ψ is to determine the magnetic field due to … the avengers 2012 blurayWebUse the fact that (ρ, J / c) is a four-vector.
