Step-by-step solution
(A) Gauss law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. So, ϕ = ∮ E → · d s → = q ∈ 0 (B) Faraday’s law explains that the direction of the current will be opposite to the direction of flux that produced it, so ∮ E → · d l → = - d ϕ B d t (C) Gauss's law for magnetism states that the magnetic flux B across any closed surface is zero, so ∮ B → · d A → = 0 (D) Ampere’s Maxwell law is stated as ∮ B → · d l → = μ 0 i c + μ 0 ∈ 0 d ϕ E d t Whe
