Vedclass · Answer

(D) Magnetic flux $(\Phi_B)$ is defined as the scalar product of the magnetic field vector $(\vec{B})$ and the area vector $(\vec{A})$, given by $\Phi_B = \vec{B} \cdot \vec{A} = BA \cos 	heta$.Since it is a dot product of two vectors, magnetic flux is a scalar quantity. Therefore, Assertion $(A)$ is false.The value of magnetic flux depends on the angle $	heta$ between the magnetic field and the area vector. Since $\cos 	heta$ can be positive, negative, or zero, the magnetic flux can also be positive, negative, or zero. Therefore, Reason $(R)$ is true.

Assertion $(A)$: Magnetic flux is a vector quantity.
Reason $(R)$: Value of magnetic flux can be positive, negative, or zero.
