Question

What does \[A\] represent in \[\Phi_B=BA\cos\theta\]?

विकल्प

• Magnetic field

• Angle between \[\vec B\] and \[\vec A\]

• Area of the surface

• Magnetic flux

Answer 1

\[A\] is the area of the surface. In a uniform magnetic field, flux is proportional to this area when the orientation is unchanged.
