What is the flux density of a magnetic field whose flux is 3000 µWb and cross-sectional area is 0.25 m2?
12,000 
T
T83,330 T
0 T
More information is needed in order to find flux density.

Flux density = Wb/m2.

What is the flux?

So simple flux density means flux per unit area.

Given:
Area = 0.25m^2.
flux = 3000*10^-6.
flux = magnetic flux density*area.
mfd = flux/area.
mfd = 3000*10^-6/.25.
mfd = 12000 ut.
Area = 0.25m^2.
flux = 3000*10^-6.
flux = magnetic flux density*area.
mfd = flux/area.
mfd = 3000*10^-6/.25.
mfd = 12000 ut.

fi=B*A
B=fi/A
B=3000/.25
B=12000
B=fi/A
B=3000/.25
B=12000

B=u*H
H=B/u
H=3000/0.25
H=12000uT
H=B/u
H=3000/0.25
H=12000uT
