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

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

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.

So simple flux density means flux per unit area.

What is the flux?

Nemai said: (Mar 20, 2014)  
Flux density = Wb/m2.

Simple flux density means flux per unit area.

mfd = flux/area.

Mag.flux density = flux/unit area.

Magnetic flux density, B = Magnetic flux,(PHI)/Area, A.

= 3000*10^-6/0.25.

= 12000 UT.

MAGNETIC FLUX DENSITY = MAGNETIC FLUX/AREA.

B = 3000*10^-6/0.25 = 12000 MICRO WEBER/M^2.

The flux passing through unit area gives flux density.

Samir Ali said: (Oct 25, 2016)  
Two type's of flux density. They are:
1) Magnetic flux density.
2) Electric flux density.

For magnetic flux density:
B(flux density) = Q(flux)/A(area).

For electric flux density:
D(flux density) = c/area.

Anurag Mishra said: (Aug 5, 2017)  
Q= B/A,
= 3000/0.25.
= 12000 micro-tesla.

Diptikanta Sahu said: (Feb 19, 2018)  
Here, D=B/A,
=3000/0.25.

Abdihalim Abdinor said: (Jan 21, 2019)  
Solution:

Flux = magnetic field/cross-sectional area.
= 3000/.25.
=12000μT.
