Question

A uniform magnetic field exists in space as B = 4 icap T . The magnetic flux through an area S= (2icap + 4 jcap) m^2 is​

Answer 1

Explanation:

ø=B . A

it is the dot product

Answer 2

• Magnetic flux is the measure of field lines that cross a given area.

• The flux can be calculated as,

                  Ф= B·A

                     =BAcosθ

• B= 4i

       S=2i + 4j

      Ф =  4i (2i + 4j)

         = 8i

       The flux will be 8 weber along the x-axis.

• When the angle between flux and area is 0°, the flux is maximum.

       When the angle between flux and area is 90°, the flux is minimum.
