Vector potential is a vector
(a) whose curl is equal to the magnetic flux density
(b) whose curl is equal to the electric field intensity
(c) whose divergence is equal to the electric potential
(d) which is equal to the vector product E × H
Question 1.2.31: Vector potential is a vector (a) whose curl is equal to the ...
The term vector potential physical stands for work done per basic cause (i.e. current element in magnetic field). Hence, \vec{A}=\frac{w}{I . \overrightarrow{d l}}
is vector so, potential is a vector. Whose curl will be equal to, \nabla \times \vec{A}=\vec{B} also, \nabla \times \vec{A}=\mu \vec{H}
Hence, the correct option is (a).
