WebMu naught is the permeability constant of the vacuum in the magnetic field. Mu naught is a physical constant that is often used in electromagnetism. The sign μ is a Greek alphabet that is used to represent mu in physics. The value of Mu naught is equal to μ0 = 4π π × 10-7 H/m. The approximated value of Mu naught is equal to 12.57 ×10-7 H/m. WebMar 18, 2024 · In simpler terms E = C where C = ∇ρ + ∂ ∂tJ Now moving to the case of B ∇ × (∇ × B) = ∇ × (J + ∂E ∂t) = ∇ × J + ∂ ∂t(∇ × E) = ∇ × J − ∂2E ∂t2 as for LHS we have ∇(∇. B) − ∇2B = ∇(0) − ∇2B Rearranging RHS and LHS we get ∇2B − ∂2B ∂t2 = − ∇ × J in simpler terms B = F where F = − ∇ × J

WebMar 31, 2024 · μ 0 = 4 π × 10 − 7 Hm -1. The speed of light is a universal physical constant and is given by. C = 3 × 10 8 ms -1. EXPLANATION: The relationship between μ 0 , ϵ 0 and velocity of light in vacuum c is. ⇒ C = 1 μ 0 ϵ 0. The above equation can be rewritten as. ⇒ μ 0 ϵ 0 = 1 C 2. Hence, option 4 is the answer.
