# Magnetic field above the plates: Babove = Bly + Bay = 0 Between the plates: Bbetween = Bly + Bzy = μ₀(J - σt) Below the plates: Bbelow = Bty + Bzy = 0 #2: ωhk | 0 | E=0 | σ | 0 +R | -R | | | Query 1.8 Page 66 Here, given current should be assumed in the larger solenoid. Blarger = μ₀n₁I₁ Φsmaller = ∫B⋅ds = (μ₀n₁I₁) * πr² Mutual inductance M = Φ/I = μ₀n₁n₂πr² Query 2.9 Page 72 ∇²E = 0, ∇²B = 0, ∇⋅E = ρ/ε₀, ∇⋅B = 0 ∇×E = -∂B/∂t, ∇×B = μ₀J + μ₀ε₀∂E/∂t Free space: ∇²E = 0, ∇²B = 0, ∇⋅E = 0, ∇⋅B = 0 ∇×E = -∂B/∂t, ∇×B = μ₀ε₀∂E/∂t A vector path; ∮A⋅dl = scalar path Optim-9 (wrong): If both are constant, then there will be no generation of EM wave. (b) uniform → independent of r (position) (wrong) Query 2.9 Page 72 Free space: ∇²E = 0, ∇²B = 0, ∇⋅E = 0, ∇⋅B = 0 ∇×E = -∂B/∂t, ∇×B = μ₀ε₀∂E/∂t A vector path; ∮A⋅dl = scalar path Optim-9 (wrong): If both are constant, then there will be no generation of EM wave.
