The magnetic flux linked with a vector area 
in a uniform magnetic field 
is
A
B
AB
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
To find the magnetic flux (A)$\Phi$ linked with a vector area, we use the formula:
$$\Phi = \vec{B} \cdot \vec{A}$$
Where:
The dot product indicates that the flux is maximized when the magnetic field is perpendicular to the area vector. Since the question's context refers to magnetic flux, the correct expression is the dot product of the magnetic field and the area vector.
Therefore, the correct option is D: $\vec{B} \cdot \vec{A}$.
$$\Phi = \vec{B} \cdot \vec{A}$$
Where:
- \u0020B is the magnetic field vector
- \u0020A is the vector area
The dot product indicates that the flux is maximized when the magnetic field is perpendicular to the area vector. Since the question's context refers to magnetic flux, the correct expression is the dot product of the magnetic field and the area vector.
Therefore, the correct option is D: $\vec{B} \cdot \vec{A}$.
