The dimensions of magnetic flux are

The net magnetic flux through any closed surface is

$A$ coil of $100$ turns and area $5 \text{ cm}^2$ is placed in a magnetic field $B = 0.2 \text{ T}$. The normal to the plane of the coil makes an angle of $60^o$ with the direction of the magnetic field. The magnetic flux linked with the coil is:

The adjoining figure shows two different arrangements in which two square wire frames are placed in a uniform constantly decreasing magnetic field $B$. The value of magnetic flux in each case is given by:

Find the magnetic flux density in $Wb/m^2$,if a magnetic flux of $2 \times 10^{-3} \ Wb$ passes through a slant area $A = 10 \ cm^2$ as shown in the figure.

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