Which of the following field equations indicate that the free magnetic charge do not exist
(a) H=\frac{1}{\mu} \nabla \times A
(b) H=\oint \frac{1 d I \times R}{4 \pi R^{2}}
(c) ∇.H =0
(d) ∇ × H = J
Question 1.2.30: Which of the following field equations indicate that the fre...
As we know, \oint B \cdot d s=0 \text { or, } \nabla \cdot B=0 [Solenoidal in nature] B = μH thus, ∇ = .(µH ) 0
∇ = .H 0
Hence, the correct option is (c).
