Question

the value of magnetic flux density which is uniform is 2T, what is the flux passing through a surface of area 0.5 m2 perpendicular to it
(1) 1 Weber
(2)10 Weber
(3) 1.25 Weber
(4) 0.25 weber
​

Answer 1

Answer:

0.25weber.............................

Answer 2

Answer:

Magnitude of magnetic field B=2 T

Area A=1.5 m

2

Since the area is perpendicular to the magnetic field, so angle between the area vector and the magnetic field θ=0

o

Magnetic flux passing through the surface ϕ=BA cosθ

⟹ ϕ=2×1.5×cos0

o

=3 Wb
